In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8850M are massively better than the AMD Radeon R3 6400T.
The Radeon HD 8850M has a 275 MHz higher core clock speed and 32 more Texture Mapping Units than the Radeon R3 6400T. This results in the Radeon HD 8850M providing 22.2 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 HD 8850M has a 275 MHz higher core clock speed and 12 more Render Output Units than the Radeon R3 6400T. This results in the Radeon HD 8850M providing 8.6 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 R3 6400T was released over a year more recently than the Radeon HD 8850M, and so the Radeon R3 6400T is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 8850M.
The Radeon HD 8850M has 2048 MB video memory, but the Radeon R3 6400T does not have an entry, so the two GPUs cannot be reliably compared in this area.
The Radeon HD 8850M has 640 Shader Processing Units and the Radeon R3 6400T has 128. However, the actual shader performance of the Radeon HD 8850M is 496 and the actual shader performance of the Radeon R3 6400T is 29. The Radeon HD 8850M having 467 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 8850M delivers a significantly smoother and more efficient experience when processing graphical data than the Radeon R3 6400T.
The Radeon HD 8850M requires 45 Watts to run and the Radeon R3 6400T requires 5 Watts. The Radeon HD 8850M requires 40 Watts more than the Radeon R3 6400T to run. The difference is significant enough that the Radeon HD 8850M may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon R3 6400T.

| Mini Review | Overview Radeon HD 8850M is a Performance Mobile Graphics Card based on the Second Revision of the GCN Architecture. Architecture The GCN 1.1 Release adds support for AMD's TrueAudio Technology which does calculations of audio effects "better" than the CPU and further improves the Powertune Technology. GPU It equips a GPU codenamed Venus PRO which has 10 Compute Units activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The Central Unit Initially Operates at 625MHz and goes up to 775MHz, in Turbo Mode. Memory The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 1000MHz. Features DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies. Power Consumption With a rated board TDP of 45W, it is suited for 17" or larger laptops. Performance Gaming benchmarks put its performance somewhat above NVIDIA's GeForce GT 750M. System Suggestions We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 8850M. | Radeon R3 6400T is an integrated Graphics Card in the APU A4 Micro-6400T Quad-Core. It is based on the Graphics Core Next Architecture and offers 128 Shader Processing Units, 8 TMUs and 4 ROPs. While the central unit is set at 300MHz, the memory bus-width will be of 64-bit, as the processor only support single channeled RAM. The memory clock runs at up to 667MHz. The Graphics Card also shares the processor's L2 Cache of 2MB. Therefore, it reduces the need to resort to its memory bandwidth. Therefore, the Graphics Card's performance depends a lot on the system configuration. Best case scenario, expect performance similar to the integrated Intel HD 2500. The card is only suited for gaming below 720p and not all modern demanding games can be played, even at least on low settings. | |||
