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.

About the AMD Radeon HD 6870 GPU

The AMD Radeon HD 6870 is an end-of-life desktop graphics card that released in Q4 2010 with a MSRP of $239. It is built on the TeraScale 2 GPU microarchitecture (codename Barts) and is manufactured on a 40 nm process.

Memory

The HD 6870 has 1,024 MB of GDDR5 memory, with a 1,050 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 134.4 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 6870 includes 1,120 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 900 MHz. Complementing the processing units are 56 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The HD 6870 occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.3a, mini-DisplayPort 1.1 display connections. AMD recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 151 W.

Benchmark Performance & Value

The HD 6870 has the 269th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 4.03% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 4,218 score and $239 launch price (MSRP) gives it a performance per dollar of 17.65. This is the 91st best in value for the 3DMark 11 Performance GPU benchmark.
