Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 1.5GB (OEM) are significantly better than the AMD Radeon HD 8760 (OEM).
The HD 8760 was released less than a year after the GTX 660, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The HD 8760 has 512 MB more video memory than the GTX 660, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 660 has superior memory performance.
The GTX 660 has 62.4 GB/sec greater memory bandwidth than the HD 8760, which means that the memory performance of the GTX 660 is much better than the HD 8760.
The Radeon HD 8760 (OEM) has 640 Shader Processing Units and the GeForce GTX 660 1.5GB (OEM) has 1152. However, the actual shader performance of the HD 8760 is 416. The GTX 660 having 736 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the HD 8760.
The Radeon HD 8760 (OEM) requires 80 Watts to run and the GeForce GTX 660 1.5GB (OEM) requires 130 Watts. We would recommend a PSU with at least 450 Watts for the GTX 660, but we do not have a recommended PSU wattage for the HD 8760. The GTX 660 requires 50 Watts more than the HD 8760 to run. The difference is significant enough that the GTX 660 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 8760.

|Mini Review||Radeon HD 8760 (OEM) is an OEM only, fast-middle-class GPU based on the GCN architecture. |
It offers 640 Shader Processing Units on a 128-bit interface of fast GDDR5. The central unit is clocked at 1000MHz. It offers 16 ROPs and 40 TMUs. It should draw up to 80 Watts.
It's, therefore, a renamed Radeon HD 7770 and should perform exactly like it.
|GeForce GTX 660 1.5GB (OEM) is a fast-middle-class to low-high-end GPU only available on OEM systems and part of the GeForce 600 Series released by NVIDIA. |
It's based on the Kepler GK104 Core, just like high-end 600 Series GPUs but with only 1152 Shader Processing Units. Its central clock is clocked at 823MHz and goes up to 888MHz on Turbo Mode. The memory clock, unlike other Kepler GK104 based GPUs, is of only 1400MHz (operating). Fast GDDR5 was obviously used and paired with a 192-bit bus.
Benchmarks indicate its performance practically identical to the regular GTX 660.
