About the AMD Radeon RX 6600M GPU
The AMD Radeon RX 6600M is a mobile graphics card that launched in Q2 2021. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 23) and is manufactured on a 7 nm process.
Memory
The RX 6600M has 8 GB of GDDR6 memory, with a 1,750 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 224 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 6600M includes 1,792 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,068 MHz and can dynamically boost its clock speed up to 2,416 MHz. It usually operates at 2,177 MHz during typical gaming workloads. Complementing the processing units are 112 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing. Additionally, the GPU features 28 ray accelerators dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 100 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The RX 6600M has the 67th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 30.47% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the AMD Radeon HD 7870 (GHz Edition) GPU
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.
