In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 250X are massively better than the AMD Radeon HD 3800 series.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The Radeon R7 250X was released over three years more recently than the HD 3800, 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 HD 3800 when running the latest games.

The Radeon R7 250X has 1536 MB more video memory than the HD 3800, 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 72 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the Radeon R7 250X is much better than the HD 3800.

The Radeon R7 250X has 640 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the Radeon R7 250X is 517 and the actual shader performance of the HD 3800 is 0. The Radeon R7 250X having 517 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R7 250X delivers a massively smoother and more efficient experience when processing graphical data than the HD 3800.

The Radeon R7 250X transistor size technology is 27 nm (nanometers) smaller than the HD 3800. This means that the Radeon R7 250X is expected to run slightly cooler and achieve higher clock frequencies than the HD 3800.

The Radeon R7 250X requires 80 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 450 Watts for the Radeon R7 250X.

GPU Mini Review

Mini ReviewRadeon 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.
Radeon HD 3800 Series is not a GPU but instead a combination between Radeon HD 3830, Radeon HD 3850 and Radeon HD 3870 whose rank is a balance between the three and that exists for System Requirements purposes only.
