About the AMD Radeon RX 6800 GPU
The AMD Radeon RX 6800 is a desktop graphics card that launched in Q4 2020 with a MSRP of $579. 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 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 includes 3,840 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,700 MHz and can dynamically boost its clock speed up to 2,105 MHz. It usually operates at 1,815 MHz during typical gaming workloads. Complementing the processing units are 240 texture mapping units (TMUs) for efficient texture filtering and 96 render output units (ROPs) for pixel processing. Additionally, the GPU features 60 ray accelerators dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The RX 6800 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 600 W to handle the GPU's thermal design power (TDP) of 250 W.
Benchmark Performance & Value
The RX 6800 has the 22nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 52.59% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 55,084 score and $579 launch price (MSRP) gives it a performance per dollar of 95.14. This is the 20th best in value for the 3DMark 11 Performance GPU benchmark.
About the AMD Radeon R9 280X GPU
The AMD Radeon R9 280X is an end-of-life desktop graphics card that released in Q4 2013 with a MSRP of $299. It is built on the GCN 1.0 GPU microarchitecture (codename Tahiti) and is manufactured on a 28 nm process.
Memory
The R9 280X has 3 GB of GDDR5 memory, with a 1,500 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 288 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 R9 280X includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 850 MHz and can dynamically boost its clock speed up to 1,000 MHz. Complementing the processing units are 128 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The R9 280X occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. AMD recommends a power supply of at least 600 W to handle the GPU's thermal design power (TDP) of 250 W.
Benchmark Performance & Value
The R9 280X has the 171st best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 10.30% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 10,792 score and $299 launch price (MSRP) gives it a performance per dollar of 36.09. This is the 73rd best in value for the 3DMark 11 Performance GPU benchmark.
