This has an impact on system temperatures. TDP (Thermal Design Power) is a measurement of how much energy is lost as heat when a GPU is running. It measures how much data can be sent at one to and from the memory. The memory bus width doesn't directly impact performance but it affects the memory bandwidth. Memory bandwidth relates to the speed at which the GPU memory can be accessed, higher speed is better as the graphics card won't need to wait for memory access before rendering a frame to the screen. Too little memory may result in stuttering as the GPU tries to swap and fit everything in memory. Memory is important for high resolutions and high resolution textures in games, if you're gaming at 4K or even 8K lots of memory is required. A higher core clock speed may cause a higher TDP however. When thermals and power delivery allow, the GPU will raise its core clock to the boost clock for even more performance. Graphics card specificationsĬore Clock speed and Boost clock speed directly affect gaming performance, typically the higher the better. Our overall benchmark score measures CPU performance in gaming and compute scenarios. Use the table to the left to compare both GPUs, the advantages and disadvantages of each are shown. In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 640 over the FirePro W4100. Heat output doesn't match power consumption directly but it's a good estimate. In addition, both the Radeon RX 640 and the FirePro W4100 have an identical TDP. If you're planning at playing games at high resolutions with high quality textures, you will need a lot of memory. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture.įurthermore, the spec sheet for both these GPUs show that the Radeon RX 640 has significantly more memory with 4 GiB of memory compared to 2 GiB. This is the frequency at which the graphics core is running at. The Radeon RX 640 has a significantly higher core clock speed. Radeon RX 640 vs FirePro W4100 comparisonįor gaming, the Radeon RX 640 graphics card is better than the FirePro W4100 in our tests.
