NVIDIA GeForce GTX 680MX (Mac Edition) vs AMD Radeon RX 7700S

The AMD Radeon RX 7700S is a mobile graphics card that launched in Q1 2023. It is built on the RDNA 3.0 GPU microarchitecture (codename Navi 33) and is manufactured on a 6 nm process.

Memory

The RX 7700S has 8 GB of GDDR6 memory, with a 2,250 MHz memory clock and a 128 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 RX 7700S includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,500 MHz and can dynamically boost its clock speed up to 2,500 MHz. It usually operates at 2,200 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 7700S has the 45th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 36.25% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
