About the AMD Radeon HD 7970 GPU

The AMD Radeon HD 7970 is an end-of-life desktop graphics card that released in Q1 2012 with a MSRP of $549. It is built on the GCN 1.0 GPU microarchitecture (codename Tahiti) and is manufactured on a 28 nm process.

Memory

The HD 7970 has 3 GB of GDDR5 memory, with a 1,375 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 264 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 7970 includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 925 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 HD 7970 occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, mini-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 HD 7970 has the 211th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 7.43% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 7,770 score and $549 launch price (MSRP) gives it a performance per dollar of 14.15. This is the 92nd best in value for the 3DMark 11 Performance GPU benchmark.

About the AMD Radeon HD 7770 (GHz Edition) GPU

The AMD Radeon HD 7770 (GHz Edition) is an end-of-life desktop graphics card that released in Q1 2012 with a MSRP of $159. It is built on the GCN 1.0 GPU microarchitecture (codename Cape Verde) and is manufactured on a 28 nm process.

Memory

The HD 7770 has 1,024 MB of GDDR5 memory, with a 1,125 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 72 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 7770 includes 640 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,000 MHz. Complementing the processing units are 40 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The HD 7770 occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, mini-DisplayPort 1.2 display connections. AMD recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 80 W.

Benchmark Performance & Value

The HD 7770 has the 298th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.96% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 3,098 score and $159 launch price (MSRP) gives it a performance per dollar of 19.48. This is the 87th best in value for the 3DMark 11 Performance GPU benchmark.
