In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R6 7300 are very slightly better than the Nvidia GeForce GT 640M LE.

The Radeon R6 7300 has a 33 MHz higher core clock speed than the GT 640M, but the GT 640M has 8 more Texture Mapping Units than the Radeon R6 7300. As a result, the GT 640M exhibits a 3.2 GTexel/s better Texture Fill Rate than the Radeon R6 7300. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon R6 7300 has a 33 MHz higher core clock speed than the GT 640M, but the GT 640M has 8 more Render Output Units than the Radeon R6 7300. As a result, the GT 640M exhibits a 3.7 GPixel/s better Pixel Fill Rate than the Radeon R6 7300. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R6 7300 was released over a year more recently than the GT 640M, and so the Radeon R6 7300 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 640M.

The GT 640M has 1024 MB video memory, but the Radeon R6 7300 does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the GeForce GT 640M LE and the Radeon R6 7300 have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GT 640M is 192 and by the Radeon R6 7300 is 133. Knowing that the shader performance of the GT 640M is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce GT 640M LE requires 20 Watts to run and the Radeon R6 7300 requires 20 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewOverview
GeForce GT 640M LE is a Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It equips a GPU Codenamed GK107 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 500MHz.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 20W, it is suited for small laptops.

Performance
Gaming benchmarks indicate its performance is on average with the older GeForce GT 555M.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 640M LE.
Radeon R6 7300 is an integrated Graphics Card in the APU A10-7300.

It is based on the Graphics Core Next Architecture and offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. While the central unit is set at 533MHz, the memory bus-width will depend on whether or not the system's RAM is dual-channeled and the operating memory clock, on its frequency. Thus, it can be either 64-bit or 128-bit and up to 800MHz.
The Graphics Card also shares the processor's L2 Cache of 4MB. Therefore, it reduces the need to resort to its memory bandwidth.

Overall, the Graphics Card's performance depends a lot on the system configuration. Best case scenario, expect performance superior to a dedicated NVIDIA GeForce GT 720M or an AMD Radeon R5 M230.
The card is thus suited for 720p gaming and some modern demanding games can be played at least on medium settings.
