In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 3000 Mobile are very slightly better than the AMD Radeon R3 6400T.

The Radeon R3 6400T was released over three years more recently than the Graphics 3000, and so the Radeon R3 6400T is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Graphics 3000 when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The Radeon R3 6400T and the HD Graphics 3000 Mobile have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Graphics 3000 has 2.1 GB/sec greater memory bandwidth than the Radeon R3 6400T, which means that the memory performance of the Graphics 3000 is marginally better than the Radeon R3 6400T.

The Radeon R3 6400T has 128 Shader Processing Units but the Graphics 3000 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon R3 6400T requires 5 Watts to run but there is no entry for the HD Graphics 3000 Mobile.

GPU Mini Review

Mini ReviewRadeon 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.
Intel® HD Graphics, simplifies your designs by eliminating additional discrete graphics hardware, while integrating stunning visuals and performance for immersive2 gaming. That’s because the graphics engine and media processing in 2nd generation Intel® Core™ i3, Core™ i5, and Core™ i7 processors are integrated right on the processor.
