6 minute read time
For the first time in a very long time I have switched over my main enthusiast rig to an AMD platform, moving away from my very familiar Intel platforms in the last decade. AMD has almost come out of nowhere with Ryzen and completely changed the game in the last few years, all culminating in the Zen 2 CPU and X570 chipset.
I have switched over to AMD’s new Ryzen 7 3700X processor and ASRock X570 Taichi motherboard, with a super-crazy high-speed PCIe 4.0 NVMe M.2 SSD that pumps up to 5GB/sec and 16GB of G.SKILL Trident Z Royal DDR4-3200 memory.
I personally play on either my 32-inch monitor with a native 2560×1440 at 144Hz or the super-high-end 4K 144Hz display, and I consistently use the GeForce RTX 2080 Ti as my personal graphics card as it is the best. I have stuck with Intel CPUs because they have, at least until now, been superior for these types of gaming workloads.
So for me to enjoy my gaming sessions of Overwatch and Apex Legends at high FPS, I have to have a great platform to maintain that performance and the new Ryzen 7 3700X and X570 combo really kicks ass. I have moved from a mix of the Intel Core i7-8700K and Core i9-9900K processors to the new Ryzen 7 3700X and in Overwatch and Apex Legends, we have near equal performance.
The benchmarks will show a little otherwise, but for the most part I have been experiencing performance that I can’t really tell between the 8700K and 9900K with the new 3700X. AMD has stepped it up to the point of enthusiasts and gamers alike are able to confidently buy a new Ryzen 3000 series CPUs and have a kick ass time.
Fan Speed on NVLink/SLI
Now that I’ve got a new high-end AMD Ryzen 7 3700X rig set up, I thought I would do some new testing with:
- NVIDIA GeForce RTX 2080 Ti in NVLink with STOCK fan speed
- NVIDIA GeForce RTX 2080 Ti in NVLink with 100% fan speed
- NVIDIA GeForce GTX 1080 Ti in SLI with STOCK fan speed
- NVIDIA GeForce GTX 1080 Ti in SLI with 100% fan speed
These tests show some interesting results, with up to 10% more performance when the fans are cranked up — keeping those hot GPUs cooler allowing GPU Boost to do its thing on Pascal, and more optimal, on Turing.

New AMD Ryzen 7 3700X Testbed
Check Out My New Digs
This is the first enthusiast grade AMD CPU powered system that I have built for myself in many years, but with the arrival of AMD’s next-gen Zen 2 architecture and its improvements in countless ways, it was time to make the switch.
AMD’s new Ryzen 3000 series CPU family are the first processors from AMD that have just wiped the floor in so many ways — I mean, we have 7nm while Intel is on 14nm. The new X570 boards have PCIe 4.0 connectivity, EVERY motherboard with an Intel chipset on the market has PCIe 3.
0. IPC performance that either gets close to, matches, or beats the price-equivalent Intel CPU.
For an enthusiast, I want as many cores as you can throw at me but the gamer and ultra-enthusiast in me wants higher CPU clock speeds so I have every part in my machine either being the best on the market, or overclocking to past that point. I want to ensure I’m getting every frame I can get.
I’ve been running an Intel Core i7-8700K for the past few years until the Core i9-9900K arrived so I made the switch, and now into the Ryzen 7 3700X. Like the 9900K I still maintain my 8C/16T but I gain near identical gaming performance (which matters to me) but I get the new X570 chipset which has PCIe 4.0.
Sure, PCIe 4.0 is useless for graphics cards right now but for storage you can hit 5GB/sec which is insane, and I want that. I won’t use it that often (to the full 5GB/sec speeds) but I damn well want it. I don’t get into cars or any other main hobbies, PCs are my everything — I want it all.
Haha.
AMD Ryzen 7 3700X + ASRock X570 Taichi
AMD’s new Ryzen 7 3700X: 8C/16T, PCIe 4.0 ready, and all on 7nm — oh and the stock cooler kicks ass.
ASRock’s new X570 Taichi motherboard is at the heart of our new Ryzen 7 3700X high-end GPU test bed.
Seriously, the G.SKILL Trident Z Royal DDR4 RAM is some of the best-looking RAM on the market.
The ASRock X570 Taichi motherboard has been serving me well through 100s of hours of benchmarking and gaming in the last few weeks, even with NVLink and SLI setups being punished on it.
The stock Wraith Prism RGB cooler that AMD provides with the retail Ryzen 7 3700X is all you need as AMD is squeezing as much as it can out of Precision Boost as it is, watercooling and AIO coolers won’t provide you with crazier overclocks without really pushing things to their limits.
RTX 2080 Ti NVLink + GTX 1080 Ti SLI
I used the GeForce RTX 2080 Ti in NVLink and GeForce GTX 1080 Ti in SLI for this testing… but I will have another article that will cover the new GeForce RTX 2080 SUPER cards in NVLink, as well as the TITAN Xp cards in SLI.
I’ll continue adding to this with Radeon RX Vega 64 in CrossFire to be tested soon, too.

Final Thoughts
Final (Fan?) Thoughts
My testing on the GeForce RTX 2080 Ti in NVLink versus the older Pascal-based GeForce GTX 1080 Ti in SLI was an interesting one, with some major highlights at the right resolutions of the sheer power of the Turing GPU architecture and super-fast GDDR6 memory.
NVIDIA’s new GeForce RTX 2080 Ti cards in NVLink shred the GTX 1080 Ti SLI setup in games like Shadow of War at 4K with a huge 110FPS average with stock fans, and even better 123FPS average when the fans are at 100%. This allows the card to stretch a little further and keep its high GPU clocks that much higher, as the card is staying cooler.
Note: I’m only testing the Founders Edition graphics cards here, with some NVLink setups from custom RTX cards coming soon. I will be updating these results with RTX 2070 SUPER and RTX 2080 SUPER cards in NVLink in the coming days and weeks, too. But the FE cards do run hotter than custom cards, so the results will definitely change.
Shadow of the Tomb Raider on the GTX 1080 Ti SLI is already good at 94-103FPS (fans at stock versus 100%) but the RTX 2080 Ti in NVLink boosts that to 125-131FPS (fans at stock versus 100%). RTX 2080 Ti in NVLink is what you’ll want for some Big Format Gaming Display (BFGD) action on a huge 65-inch 4K 120Hz TV or the super-fast 4K 144Hz G-Sync gaming monitors for Shadow of the Tomb Raider.
I’ve got some interesting results with SLI and NVLink setup with Overwatch, something I need to spend some time with testing but I was getting virtually 100% scaling at 4K and even 8K. I can load the game up to maximum resolution scaling (200%) with maximum AA applied and it was pushing 98-100% GPU consumption on both cards. Those results are in the making now.
Wrapping up, increasing the fan speed on SLI and NVLink setups is an obvious one and a move that will net you some more performance and in some cases up to 10% more which is a big win for an already high-end setup.

Nvidia GeForce GTX 1080Ti SLI vs RTX 2080Ti | What’s The Difference?
by Jim Eddy
Some gamers think that NVIDIA’s newest flagship 1080Ti SLI is the best solution, but others believe that the 2080 Ti is more than enough. 1080Ti SLI gives gamers the ability to game at 3840×2160 resolutions in higher detail, while 2080 Ti cards offer performance at natively 3440×1440. 1080 ti SLI is a graphics solution with two cards in a single unit in a computer, while 2080 Ti SLI has two cards in a single unit in a computer.
GTX 1080Ti SLI vs RTX 2080Ti – Which One?
It’s time to put 1080ti SLI and 2080 Ti up against each other. With this in mind, we will examine the 1080ti SLI vs.
2080 ti to establish which is a better option for gamers looking to invest in a new graphics card. This article also discusses which GPU configuration is best for you.
Features
GTX 1080 SLI
The Nvidia GeForce GTX 1080 SLI graphics card is an SLI configuration of two GTX 1080 graphics cards. Each GPU produces one frame at a time (AFR mode), however, most games rely on a decent driver profile. As a result, performance can range from no gain over a single GTX 1080 to up to 90% improvements. Micro stuttering can occur when this combination is used.
- 3-way and 4-way multi-GPU SLI setups
- NVidia’s new Pascal GPU-based graphics cards
- Transfer data between them at 650MHz
- The gaming experience at 4K-plus resolutions
- Memory Bus Width 256 Bit
- 144000 million Transistor count
RTX 2080 Ti
NVIDIA’s GeForce RTX 2080 Ti is a high-end graphics card for gamers.
The card supports DirectX 12 Ultimate and is built on a 12 nm process and based on the TU102 graphics processor in its TU102-300A-K1-A1 model. All modern games will run on the GeForce RTX 2080 Ti as a result of this.
- Ray tracing is powered by 68 RT Cores.
- 544 Tensor Cores bring AI into the mix
- Deep Learning Super Sampling
- Maintain a frame rate between 34 fps to 117 fps
- Introduces the world’s first dual-fan cooling system
- Features 18.6 Billion transistors
- 272 texture mapping units
- Operates at a base clock of 1410 MHz
- The card has 11 GB GDDR6 memory
The following is a quick comparison of the differences and similarities between the GTX 1080TI Sli and the GTX 2080TI. You can immediately figure out what features they have and whether they match your needs.
| GPU | GTX 1080TI Sli | RTX 2080 Ti |
| Cores | 3840 CUDA Cores | 4352 CUDA cores |
| Base Clock | 1582 MHz | 1350MHz |
| Memory Speed | 10000 MHz | 1545 MHz |
| Memory Bus | 352-Bit bus | 352-Bit bus |
| Memory Type | GDDR5 | GDDR6 |
| Transistors | 14400 Million | 18,600 Million |
| Notebook Size | large | large |
| Boost Clock | 2. 2GHz |
1710MHz |
| Core Speed | 1556 – 1733 (Boost) MHz | 1350 – 1545(Boost)MHz |
| Texture Units | 224 | 272 |
In the table above, I tried to put some significant aspects. You can base your choice on such characteristics.
Gaming
Now it’s time to dive into the main reason you are here. What’s the gaming performance for both GPUs?
Apex Legend
This is a free-to-play battle royale game that uses high graphics. While playing it on the 1080 TI SLI, there were many issues & stutters. But switching to 2080, we found that the performance was highly improved. Maybe the drivers weren’t optimized for the performance.
Call of Duty
This is also a multiplayer game from Activision. While playing this game 2080 is still the better choice. But there was much better scaling for 1080 TI SLI this time. But performance-wise, 2080 takes it by the bell.
Valotrant
This is a 5 vs 5 first-person shooter game from RIOT.
Here the game was not optimized for the 1080 TI SLI. rather 2080 got the best out of the game. High frame rates plus maxed-out settings did great.
Support
Although on paper SLI looks cool, NVIDIA is turning its backs on SLI support. Poor SLI support makes the technology dead. Even if you get the proper setup, you will never get 100% out of this setup.
Most games are not supporting SLI. This is a huge factor for everyone to consider. Even some games perform better with only single 1080 TI. On the other hand, 2080 is just a single GPU. The performance is outstanding with the single unit 2080 GPU.
Budget
GTX 1080TI Sli
The GeForce GTX 1080 Ti SLI will easily outperform most games at 1080p. Set your screen resolution to 1440p or 4K to enjoy AAA game images. It was initially available, making it less expensive than the RTX 2080TI.
RTX 2080 Ti
It contains 4352 NVIDIA CUDA cores with a clock speed of 1545 MHz and a processing power of 12 nm.
It also includes 14 GB of GDDR6X memory, which is one of the fastest memory technologies available. It’s a whirlwind of activity at roughly 14 Gbps. It has a higher MSRP of 999 dollars than the GTX 1080 Ti SLI.
Last words
The RTX 2080 from Nvidia is a better card than the GTX 1080 Ti because it uses newer technologies and provides better, faster performance. The 2080 Ti outperformed the 1080 Ti by 27%, while the 1080 Ti outperformed the 980 Ti by 74%. As a result, we recommend getting an RTX 2080 Ti instead of a GTX 1080 Ti because the RTX 2080 Ti has a faster core clock and graphics clock speed.

Hello, dear readers of the site Uspei.com. Straight to the point: four video cards, a top processor, 4K resolution and a lot of tests. It’s all waiting for you in today’s episode. And the numbers will surprise you. Promise!
As you may have guessed from the title of the article, today we are testing the SLI of two GTX 1080s, the top of the previous generation GTX 1080Ti and this year’s new RTX 2080.
I recorded over 100 gigabytes of video with tests and benchmarks in games, spending more than a week analyzing the results .
Many people wrote that the new generation of video cards is too expensive and does not provide the performance boost promised by NVIDIA. And here I completely agree. And completely crazy ideas sounded, but one of them put me in a stupor. So I decided to test it in practice.
To the table of contents ↑
Test conditions
This proposal is to replace one 2080 with two 1080s in SLI. The configuration of the test machine is on your screen, I don’t see the point in pronouncing all this. I will only say that the system is set to SSD HyperX Savage , and I ran games with NVMe from ADATA.
I took the power supply with a large margin. I caught my eye on a 1300W Kenweiipc mining variant with 90 Plus Gold certification. And yes, the manufacturer claims a maximum efficiency of up to 92%.
It is enough for SLI of two 1080s. A system with other video cards does not consume more than 500 watts.
Let’s move on to the description of the test process . 4K resolution, settings in all games Ultra or very high, results for all games were summed up after 5 iterations with the calculation of the average value.
On the last build of Windows, the SLI connection was unstable, so it was decided to roll it back to version 17124.
In all DirectX games, 11 (eleventh) was used, since version 12 (twelfth) crashed and errors were thrown.
Since my LG monitor is a cool Full HD monitor, it’s time to use ‘s Dynamic Super Resolution (DSR) feature.
The dual 1080 setup was forced to use both video cards for all games in the NVIDIA Inspector settings.

Assassin’s Creed Origin
The average frame rate for 1080 SLI is 34 frames, which is far behind the other two cards.
Between 1080 Ti and 2080 there is practically no difference in the results. And you will observe this in almost all tests. In terms of 1% and 0.1% (zero one point and one tenth of a percent), two 1080s have big problems, and you can generally forget about the smoothness of the game. But, gritting your teeth, it is quite possible to play the game on a large 4K TV.
Table of contents ↑
Battlefield 1
Imagine my surprise when the SLI setup outperformed last year’s flagship and this year’s predecessor. 79 frames on average, versus 73 and 69. However, pay attention to the frame time. It is very unstable, the picture comes out twitchy and torn. Therefore, it seems that you are playing at 30 FPS.
Back to contents ↑
Final Fantasy XV
Only the fight scene was tested. And again, the console frame rate for two 1080 and the advantage of the other two video cards is an average of 25%.
1080 SLI scores 3089 in final scorepoints, GTX 1080 Ti — 4303, RTX 2080 only 1% more, which is within the margin of error.
Back to contents ↑
PlayerUnkNowns BattleGround
SLI in PUBG works very badly. Therefore, the difference with the GTX 1080 Ti is almost twofold. What was surprising is that in the same location, the minimum FPS of the GTX 1080 Ti was 10-15% higher compared to the RTX 2080, but the rare drawdowns were more serious. Therefore, they share the championship medal again.

Ray Tracing was enabled for the RTX, so some of its power was handled by shadows and highlights. If you turn it off, the difference between the cards will disappear again. And for SLI, the situation is still the same — she grazes the rear, hoping to win back in The Witcher.

The Witcher 3
The game is very well optimized, and everyone knows it very well.
And just then SLI takes the lead and bypasses 1080 Ti by 15%, and RTX by as much as 20%. But the values of rare and very rare events for all video cards are within the margin of error.

Ghost Recon Wildlands
In this game, the second type of alternative rendering mode must be activated in the NVIDIA panel for SLI. But that didn’t help much either. Although the average frame rate is higher, rare and very rare events jumped from 4 to 11. On the other two cards, although the console FPS was at 4K, everything was smooth and without noticeable friezes and starters.
As for the overall consumption of the system with different graphics cards, we can say that the RTX 2080 graphics card chip has been made more energy efficient. With it, the entire PC consumed no more than 350 watts. With the GTX 1080 Ti, it’s a bit more — about 400 watts peak. However, for a bunch of two 1080s, prepare a power supply with a power of at least 800 watts.
