About the NVIDIA GeForce GT 640M LE GPU
The NVIDIA GeForce GT 640M LE is an end-of-life mobile graphics card that released in Q1 2012. It is built on the Kepler GPU microarchitecture (codename GK107) and is manufactured on a 28 nm process.
Memory
The GT 640M LE has 1,024 MB of DDR3 memory, with a 900 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 28.8 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.
Cores and Clock Speeds
The GT 640M LE includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 500 MHz and can dynamically boost its clock speed up to 570 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 20 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 640M LE has the 428th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.20% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the AMD Radeon RX 7900 XTX GPU
The AMD Radeon RX 7900 XTX is a desktop graphics card that launched in Q4 2022 with a MSRP of $999. It is built on the RDNA 3.0 GPU microarchitecture (codename Navi 31) and is manufactured on a 5 nm process.
Memory
The RX 7900 XTX has 24 GB of GDDR6 memory, with a 2,500 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 960 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.
Cores and Clock Speeds
The RX 7900 XTX includes 6,144 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,929 MHz and can dynamically boost its clock speed up to 2,498 MHz. It usually operates at 2,365 MHz during typical gaming workloads. Complementing the processing units are 384 texture mapping units (TMUs) for efficient texture filtering and 192 render output units (ROPs) for pixel processing. Additionally, the GPU features 192 AI accelerators optimized for AI workloads and 96 ray accelerators dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The RX 7900 XTX occupies 2 PCIe expansion slots. It supports HDMI 2.1a, DisplayPort 2.1, USB Type-C display connections. AMD recommends a power supply of at least 750 W to handle the GPU's thermal design power (TDP) of 355 W.
Benchmark Performance & Value
The RX 7900 XTX has the 4th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 79.66% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 83,322 score and $999 launch price (MSRP) gives it a performance per dollar of 83.41. This is the 33rd best in value for the 3DMark 11 Performance GPU benchmark.
