About the AMD Radeon HD 8790M GPU

The AMD Radeon HD 8790M is an end-of-life mobile graphics card that released in Q2 2013. It is built on the GCN 1.0 GPU microarchitecture (codename Mars) and is manufactured on a 28 nm process.

Memory

The HD 8790M has 2 GB of GDDR5 memory, with a 1,000 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 64 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 HD 8790M includes 384 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 900 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.

Benchmark Performance

The HD 8790M has the 349th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.09% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon RX 6800S GPU

The AMD Radeon RX 6800S is a mobile graphics card that launched in Q1 2022. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 23) and is manufactured on a 7 nm process.

Memory

The RX 6800S 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 6800S includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,800 MHz and can dynamically boost its clock speed up to 2,100 MHz. It usually operates at 1,975 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 GPU has a thermal design power (TDP) of 100 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The RX 6800S has the 54th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 34.51% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
