About the AMD Radeon RX 6500 XT GPU
The AMD Radeon RX 6500 XT is a desktop graphics card that launched in Q1 2022 with a MSRP of $199. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 24) and is manufactured on a 6 nm process.
Memory
The RX 6500 XT has 4 GB of GDDR6 memory, with a 2,248 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 143.9 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 6500 XT includes 1,024 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,310 MHz and can dynamically boost its clock speed up to 2,815 MHz. It usually operates at 2,610 MHz during typical gaming workloads. Complementing the processing units are 64 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing. Additionally, the GPU features 16 ray accelerators dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The RX 6500 XT occupies 2 PCIe expansion slots. It supports HDMI 2.1, DisplayPort 1.4a display connections. AMD recommends a power supply of at least 300 W to handle the GPU's thermal design power (TDP) of 107 W.
Benchmark Performance & Value
The RX 6500 XT has the 102nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 21.94% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 22,954 score and $199 launch price (MSRP) gives it a performance per dollar of 115.35. This is the 9th best in value for the 3DMark 11 Performance GPU benchmark.
About the NVIDIA GeForce GT 645M GPU
The NVIDIA GeForce GT 645M is an end-of-life mobile graphics card that released in Q4 2012. It is built on the Kepler GPU microarchitecture (codename GK107) and is manufactured on a 28 nm process.
Memory
The GT 645M has 2 GB 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 645M includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 709 MHz and can dynamically boost its clock speed up to 780 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 32 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 645M has the 372nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.76% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
