In this article, we’ll be taking a look at two of those GPUs and comparing their price to performance: AMD RX 580 vs Nvidia GTX 1660 Ti
| AMD RX 580 | NVIDIA GTX 1660 Ti |
| PROS | PROS |
| Faster than Radeon RX 480. Lower multi-monitor and video playback power use. Similar starting price as Radeon RX 480. | Great performance at 1920 x 1080. Acceptable frame rates at 2560 x 1440. Retains Turing’s video encode/decode acceleration features. 120W board power compares favorably to AMD competition. |
| CONS | CONS |
| Higher power consumption than Radeon RX 480 under load. The new name may confuse some | No RT/Tensor cores mean you won’t be able to try ray tracing or DLSS |
RX 580 vs GTX 1660 Ti: Specs
| RX 580 | GTX 1660 Ti | |
| S.Proces/ C.Cores | 2304 | 1536 |
| Base Clock | 1257 MHz | 1500 MHz |
| Boost Clock | 1340 MHz | 1875 MHz |
| Memory | 8GB GDDR5 | 6GB GDRR6 |
| Interface | 256-Bit | 192 – bit |
| Bandwidth | 256 GB/S | 288.1 GB/s |
NOTE:
Things like Cuda cores, stream processors, and clock speeds are not directly comparable because both are based on different architectures.
The RX 580 is based on the 14nm GCN 4th gen architecture and was released in April 2017.
Something to take note of though is that the GTX 1660 Ti has 6GB of GDDR6 memory, while the RX 580 has 8GB, so we may see that additional memory comes in use at higher resolutions with higher settings in some titles
The GTX 1660 Ti was released in February of 2019 at a launch price of $219. It runs a core clock of 1500 MHz, has 6GB of GDDR6 memory, and a TDP of 120W.
RX 580 vs GTX 1660 Ti: Performance
For the testing, I’m using the MSI GTX 1660 Ti and Sapphire RX 580. Expect slightly different results with different models.
The system that I’m testing with has an i7-8700K CPU on Z370 Motherboard, along with 16GB RAM DDR4-2800MHz.
The Following games are tested at 1080p and 1440p. The FPS are shown are average.
Shadow of the Tomb Raider
Shadow of the Tomb Raider was tested running through the start of the game, with the same test pass completed each time. With the Ultra preset, at 1080p the 1660 TI was just 26FPS faster than the RX 580, and 16FPS ahead at 1440p.
Deus Ex: Mankind Divided
Deus Ex was tested with the game’s built in benchmark. At 1080p the Ti was 11FPS ahead of the RX 580, increasing to a 8FPS lead at 1440p.
F1 2018
F1 2018 was tested with all graphical settings at maximum, and at 1080p and 1440p there was huge difference between the two.
Far Cry 5
Far Cry 5 was tested with the game’s benchmark tool, and this title was seeing an above-average increase to performance with the Ti, granted it’s still a somewhat small difference, with the 1660 Ti was about 20FPS ahead at both resolutions.
Ghost Recon Wildlands
Ghost Recon Wildlands was tested in campaign mode with the highest ultra preset. There was a big difference between the two with this game, just a 15FPS boost at 1080p with the Ti and 12FPS at 1440p.
GTA 5
GTA 5 was tested using the built-in benchmark at very high settings and was another with big differences between the two. The Ti was just 39FPS faster at 1080p, and 28FPS at 1440p.
Hellblade: Senua’s Sacrifice
Hellblade was tested using the replay feature, with the exact same replay file used for each test. Big noticeable differences here, at 1080p and 1440p.
Monster Hunter World
Monster Hunter World was tested with the built-in benchmark. Just looking at the results I want to say there’s a major difference. The Ti coming out 21FPS ahead at 1080p and 13FPS ahead at 1440p.
Rainbow Six Siege
Rainbow Six Siege was tested as a Vulkan title using the built-in benchmark. This game was giving good playable frame rates on both graphics cards. Anyways the GTX 1660 ti was a clear winner in this tittle.
Witcher 3
The Witcher 3 was tested with ultra settings. At 1080p the Ti was 30FPS ahead of the RX 580, lowering ever so slightly to 18FPS higher at 1440p.
RX 580 or GTX 1660 Ti: Which is Better?
The results are in favor of GTX 1660 Ti. The MSRP is meant to be $200 USD for the RX 580 and $280 for the GTX 1660 Ti. Paying %80 more will give you better power and performance. Yes, there is a good advantage to RX 580 is that 8GB of VRAM. The 1660 Ti it would be my pick between the two if I was buying today. In my opinion the GTX 1660 Ti is better value as this was performing 28% better in performance.
