AMD Radeon HD 7770 (GHz Edition) vs AMD Radeon RX 7700 XT

The AMD Radeon RX 7700 XT is a desktop graphics card that launched in Q3 2023 with a MSRP of $449. It is built on the RDNA 3.0 GPU microarchitecture (codename Navi 32) and is manufactured on a 5 nm process.

Memory

The RX 7700 XT has 12 GB of GDDR6 memory, with a 2,250 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 432 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 7700 XT includes 3,456 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,435 MHz and can dynamically boost its clock speed up to 2,544 MHz. It usually operates at 2,171 MHz during typical gaming workloads. Complementing the processing units are 216 texture mapping units (TMUs) for efficient texture filtering and 96 render output units (ROPs) for pixel processing. Additionally, the GPU features 108 AI accelerators optimized for AI workloads and 54 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RX 7700 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 550 W to handle the GPU's thermal design power (TDP) of 245 W.

Benchmark Performance & Value

The RX 7700 XT has the 19th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 54.82% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 57,340 score and $449 launch price (MSRP) gives it a performance per dollar of 127.71. This is the 5th best in value for the 3DMark 11 Performance GPU benchmark.
