In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6870 Sapphire Dirt3 Edition are marginally better than the Nvidia GeForce GTX 750 Gigabyte OC 1GB Edition.

The GTX 750 has a 138 MHz higher core clock speed than the HD 6870, but the HD 6870 has 24 more Texture Mapping Units than the GTX 750. As a result, the HD 6870 exhibits a 17.6 GTexel/s better Texture Fill Rate than the GTX 750. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 750 has a 138 MHz higher core clock speed than the HD 6870, but the HD 6870 has 16 more Render Output Units than the GTX 750. As a result, the HD 6870 exhibits a 12.5 GPixel/s better Pixel Fill Rate than the GTX 750. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 750 was released over three years more recently than the HD 6870, and so the GTX 750 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 6870 when running the latest games.

The Radeon HD 6870 Sapphire Dirt3 Edition and the GeForce GTX 750 Gigabyte OC 1GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 6870 has 54.2 GB/sec greater memory bandwidth than the GTX 750, which means that the memory performance of the HD 6870 is much better than the GTX 750.

The Radeon HD 6870 Sapphire Dirt3 Edition has 1120 Shader Processing Units and the GeForce GTX 750 Gigabyte OC 1GB Edition has 512. However, the actual shader performance of the HD 6870 is 515 and the actual shader performance of the GTX 750 is 786. The GTX 750 having 271 better shader performance is not particularly notable, as altogether the HD 6870 performs better when taking into account other relevant data.

The GTX 750 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the GTX 750 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870. While they exhibit similar graphical performance, the GTX 750 should consume less power than the HD 6870.

The Radeon HD 6870 Sapphire Dirt3 Edition requires 251 Watts to run but there is no entry for the GeForce GTX 750 Gigabyte OC 1GB Edition. We would recommend a PSU with at least 500 Watts for the HD 6870 and a PSU with at least 400 Watts for the GTX 750. The HD 6870 has been recommended a PSU with 100 Watts more than the GTX 750. The difference is significant enough that the HD 6870 may have an adverse affect on your yearly electricity bills in comparison to the GTX 750.

GPU Mini Review

Mini ReviewRadeon HD 6870 Sapphire Dirt3 Edition is a special edition of the high-end Radeon HD 6870 that features a small increase in the core-clock and a new cooling system called WindForce 3X.
The GPU runs cooler but the performance boost is of only 1% according to most benchmarks.
GeForce GTX 750 Gigabyte OC 1GB Edition is a special edition of the fast-middle-class GeForce GTX 750.
This edition comes with a custom cooling cooling solution which by itself will allow a slight performance boost, as GeForce GTX 750 benefits from the GPU Boost 2.0 technology.
Furthermore, it comes overclocked out of the box in the central unit that was raised from 1020MHz to 1058MHz, while the Turbo Boost is now of 1137MHz, instead of 1085MHz. The operating memory clock was left untouched.
Further overclocking can be achieved easily, as the GPU has great OC potential.
Benchmarks indicate its performance is around 4% better than the reference NVIDIA GeForce GTX 750 and thus this card is slightly faster than Radeon R7 260X.
