In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 250X are massively better than the Nvidia GeForce 8600 GTS 256MB.

The Radeon R7 250X has a 275 MHz higher core clock speed and 24 more Texture Mapping Units than the 8600 GTS. This results in the Radeon R7 250X providing 27.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon R7 250X has a 275 MHz higher core clock speed and 8 more Render Output Units than the 8600 GTS. This results in the Radeon R7 250X providing 9.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 250X was released over three years more recently than the 8600 GTS, and so the Radeon R7 250X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8600 GTS when running the latest games.

The Radeon R7 250X has 1792 MB more video memory than the 8600 GTS, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon R7 250X also has superior memory performance overall.

The Radeon R7 250X has 40 GB/sec greater memory bandwidth than the 8600 GTS, which means that the memory performance of the Radeon R7 250X is noticeably better than the 8600 GTS.

The GeForce 8600 GTS 256MB has 32 Shader Processing Units and the Radeon R7 250X has 640. However, the actual shader performance of the 8600 GTS is 54 and the actual shader performance of the Radeon R7 250X is 517. The Radeon R7 250X having 463 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R7 250X delivers a significantly smoother and more efficient experience when processing graphical data than the 8600 GTS.

The Radeon R7 250X transistor size technology is 52 nm (nanometers) smaller than the 8600 GTS. This means that the Radeon R7 250X is expected to run massively cooler and achieve higher clock frequencies than the 8600 GTS.

The GeForce 8600 GTS 256MB requires 75 Watts to run and the Radeon R7 250X requires 80 Watts. We would recommend a PSU with at least 350 Watts for the 8600 GTS and a PSU with at least 450 Watts for the Radeon R7 250X. The Radeon R7 250X requires 5 Watts more than the 8600 GTS to run. The difference is not significant enough for the Radeon R7 250X to have a noticeably larger impact on your yearly electricity bills than the 8600 GTS.

GPU Mini Review

Mini ReviewGeForce 8600 GTS is a fast-middle-class GFX based on the 80nm variant of the first-shader unified architecture.
It's based on the G84 Core and offers 32 Shader Processing Units, 16 TMUs and 8 ROPs, on a 128-bit memory interface of GDDR3. The central unit runs at 675MHz and the memory clock operates 1000MHz. It will consume no more than 75 Watt.
It's therefore a further clocked GeForce 8600 GT and should be significantly faster.
This GPU is only suited for a 1024x768 (or less) resolution. Today's games will run at medium settings although extremely demanding games might not run at all. DirectX 11 based games aren't supported and its performance will decrease drastically, as the resolution increases.
Radeon R7 250X is a fast-middle-class Graphics Card based on the Graphics Core Next architecture. It offers the Cape Verde XT GPU.
The Cape Verde XT Core is a GCN 1.1 GPU and was first seen on Radeon HD 7770 and then re-used in the OEM only Radeon HD 8760.
It offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bits memory interface of fast GDDR5.
Radeon R7 250X comes clocked at 950MHz (though there might be some 1GHz versions) and has its operating memory clock set at 1125MHz. The rated TDP board is of 80W and the release price around $99.
This card should come in 1GB and 2GB versions, though both will offer the same performance.
Its performance has proven to be exactly like Radeon HD 7770 GHz Edition (if clocked at 1GHz) and thus this card is not suited for 1080p gaming but it can handle 720p with ease. The 950MHz versions will be around 3% slower.
