About the AMD Radeon RX 7900 XT GPU
The AMD Radeon RX 7900 XT is a desktop graphics card that launched in Q4 2022 with a MSRP of $899. 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 XT has 20 GB of GDDR6 memory, with a 2,500 MHz memory clock and a 320 bit interface. This gives it a memory bandwidth of 800 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 XT includes 5,376 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,387 MHz and can dynamically boost its clock speed up to 2,394 MHz. It usually operates at 2,025 MHz during typical gaming workloads. Complementing the processing units are 336 texture mapping units (TMUs) for efficient texture filtering and 192 render output units (ROPs) for pixel processing. Additionally, the GPU features 168 AI accelerators optimized for AI workloads and 84 ray accelerators dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The RX 7900 XT 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 700 W to handle the GPU's thermal design power (TDP) of 300 W.
Benchmark Performance & Value
The RX 7900 XT has the 5th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 72.56% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 75,896 score and $899 launch price (MSRP) gives it a performance per dollar of 84.42. This is the 31st best in value for the 3DMark 11 Performance GPU benchmark.
About the NVIDIA GeForce GT 420M GPU
The NVIDIA GeForce GT 420M is an end-of-life mobile graphics card that released in Q3 2010. It is built on the Fermi GPU microarchitecture (codename GF108) and is manufactured on a 40 nm process.
Memory
The GT 420M has 1,024 MB of DDR3 memory, with a 800 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 25.6 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 420M includes 96 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 500 MHz. Complementing the processing units are 16 texture mapping units (TMUs) for efficient texture filtering and 4 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 23 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 420M has the 490th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.65% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
