About the AMD Radeon RX 6800 XT GPU
The AMD Radeon RX 6800 XT is a desktop graphics card that launched in Q4 2020 with a MSRP of $649. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 21) and is manufactured on a 7 nm process.
Memory
The RX 6800 XT has 16 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 512 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 6800 XT includes 4,608 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,825 MHz and can dynamically boost its clock speed up to 2,250 MHz. It usually operates at 2,015 MHz during typical gaming workloads. Complementing the processing units are 288 texture mapping units (TMUs) for efficient texture filtering and 128 render output units (ROPs) for pixel processing. Additionally, the GPU features 72 ray accelerators dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The RX 6800 XT occupies 2 PCIe expansion slots. It supports HDMI 2.1, DisplayPort 1.4a, 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 6800 XT has the 25th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 49.76% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 52,046 score and $649 launch price (MSRP) gives it a performance per dollar of 80.19. This is the 36th best in value for the 3DMark 11 Performance GPU benchmark.
About the NVIDIA GeForce GT 445M GPU
The NVIDIA GeForce GT 445M is an end-of-life mobile graphics card that released in Q3 2010. It is built on the Fermi GPU microarchitecture (codename GF106) and is manufactured on a 40 nm process.
Memory
The GT 445M has 3 GB of DDR3 memory, with a 800 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 38.4 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 445M includes 144 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 590 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 24 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 35 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 445M has the 439th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.10% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
