About the AMD Radeon RX 6600 XT GPU
The AMD Radeon RX 6600 XT is a desktop graphics card that launched in Q3 2021 with a MSRP of $379. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 23) and is manufactured on a 7 nm process.
Memory
The RX 6600 XT has 8 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 256 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 6600 XT includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,968 MHz and can dynamically boost its clock speed up to 2,589 MHz. It usually operates at 2,359 MHz during typical gaming workloads. Complementing the processing units are 128 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing. Additionally, the GPU features 32 ray accelerators dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The RX 6600 XT occupies 2 PCIe expansion slots. It supports HDMI 2.1, DisplayPort 1.4a display connections. AMD recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 160 W.
Benchmark Performance & Value
The RX 6600 XT has the 41st best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 37.33% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 39,051 score and $379 launch price (MSRP) gives it a performance per dollar of 103.04. This is the 14th best in value for the 3DMark 11 Performance GPU benchmark.
About the AMD Radeon RX 7900 XTX GPU

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.
