Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7500G are marginally better than the AMD Radeon HD 8450G.
The Radeon HD 8450G was released less than a year after the Radeon HD 7500G, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The Radeon HD 8450G and the Radeon HD 7500G have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The Radeon HD 8450G has 4.3 GB/sec greater memory bandwidth than the Radeon HD 7500G, which means that the memory performance of the Radeon HD 8450G is marginally better than the Radeon HD 7500G.
The Radeon HD 8450G has 192 Shader Processing Units and the Radeon HD 7500G has 256. However, the actual shader performance of the Radeon HD 8450G is 102 and the actual shader performance of the Radeon HD 7500G is 84. The Radeon HD 8450G having 18 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 8450G delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon HD 7500G.
The Radeon HD 8450G requires 35 Watts to run and the Radeon HD 7500G requires 17 Watts. The Radeon HD 8450G requires 18 Watts more than the Radeon HD 7500G to run. The difference is not significant enough for the Radeon HD 8450G to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7500G.

|Mini Review||Radeon HD 8450G is an integrated mobile GPU, first seen on the APU A6-5350M, based on the 32nm, Terascale 3 architecture. |
It offer 192 Shader Processing Units, 12 TMUs and 4 ROPs, on a DDR3 memory interface of either a 128-bit bus width, if the laptop system RAM's is dual-channelled, or a 64-bit bus width, if not. The central units runs at 533MHz and goes up to 720MHz, in Turbo Mode. The memory clock can operate up to 800MHz, as the max memory supported by the CPU is DDR3-1600.
Its performance depends somewhat on whether or not the memory is dual-channelled. Benchmarks put its performance on level with today's entry-level dedicated GPUs such as GeForce GT 610M or Radeon HD 7470M. Therefore, modern some demanding games can be played with medium detail but most will require further reduced settings.
|Radeon HD 7500G is an integrated GPU on the entry-level ULV Trinity CPUs. |
It's based on the 32nm Terascale 3 architecture and offers 256 Shader Processing Units, 16 TMUs and 8 ROPs. The memory interface will depend on whether or not the laptop's system RAM is dual channelled (128-bit if so, 64-bit, if not) and the operating memory clock can be up to 667MHz (max speed supported by the CPU). The central unit runs at 327MHz and will go up to 424MHz in Turbo Mode. Expect a TDP of up to 17 Watt.
Its performance is below Intel HD 4000 Graphics but is slightly above next in series - Radeon HD 7520G, despite the naming, due to the extra Shaders which prove useful in most of today's modern games.
Most of today's modern games will have to be played at the lowest settings, while extremely demanding games (e.g. Crysis 3) are most likely unplayable.
