The AMD Radeon HD 7870 (GHz Edition) is an end-of-life desktop graphics card that released in Q1 2012 with a MSRP of $349. It is built on the GCN 1.0 GPU microarchitecture (codename Pitcairn) and is manufactured on a 28 nm process.
Memory
The HD 7870 has 2 GB of GDDR5 memory, with a 1,200 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 153.6 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 7870 includes 1,280 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 80 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The HD 7870 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 450 W to handle the GPU's thermal design power (TDP) of 175 W.
Benchmark Performance & Value
The HD 7870 has the 226th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 5.92% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 6,194 score and $349 launch price (MSRP) gives it a performance per dollar of 17.75. This is the 90th best in value for the 3DMark 11 Performance GPU benchmark.
