In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 250X are massively better than the AMD Radeon HD 4650 Asus Low Profile Edition.

The Radeon R7 250X has a 350 MHz higher core clock speed and 8 more Texture Mapping Units than the HD 4650. This results in the Radeon R7 250X providing 18.8 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 350 MHz higher core clock speed and 8 more Render Output Units than the HD 4650. This results in the Radeon R7 250X providing 10.4 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 HD 4650, 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 4650 when running the latest games.

The Radeon R7 250X has 1024 MB more video memory than the HD 4650, 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 59.2 GB/sec greater memory bandwidth than the HD 4650, which means that the memory performance of the Radeon R7 250X is much better than the HD 4650.

The Radeon R7 250X has 640 Shader Processing Units and the Radeon HD 4650 Asus Low Profile Edition has 320. However, the actual shader performance of the Radeon R7 250X is 517 and the actual shader performance of the HD 4650 is 125. The Radeon R7 250X having 392 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 4650.

The Radeon R7 250X transistor size technology is 27 nm (nanometers) smaller than the HD 4650. This means that the Radeon R7 250X is expected to run slightly cooler and achieve higher clock frequencies than the HD 4650.

The Radeon R7 250X requires 80 Watts to run and the Radeon HD 4650 Asus Low Profile Edition requires 48 Watts. We would recommend a PSU with at least 450 Watts for the Radeon R7 250X and a PSU with at least 400 Watts for the HD 4650. The Radeon R7 250X requires 32 Watts more than the HD 4650 to run. The difference is significant enough that the Radeon R7 250X may have a slight adverse affect on your yearly electricity bills in comparison to the HD 4650.

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 4650 Asus Low Profile Edition is a special edition of the middle-class Radeon HD 4650.
This edition comes optimized for lower noise production but has no overclocking out of the box and so it performs like any other Radeon HD 4650.
