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.
About the AMD Radeon R5 M255 GPU
The AMD Radeon R5 M255 is an end-of-life mobile graphics card that released in Q4 2014. It is built on the GCN 3.0 GPU microarchitecture (codename Topaz) and is manufactured on a 28 nm process.
Memory
The R5 M255 has 2 GB of DDR3 memory, with a 1,000 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 32 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 R5 M255 includes 384 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 925 MHz and can dynamically boost its clock speed up to 940 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.
Benchmark Performance
The R5 M255 has the 380th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.70% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
