About the AMD Radeon HD 7850 GPU
The AMD Radeon HD 7850 is an end-of-life desktop graphics card that released in Q1 2012 with a MSRP of $249. It is built on the GCN 1.0 GPU microarchitecture (codename Pitcairn) and is manufactured on a 28 nm process.
Memory
The HD 7850 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 7850 includes 1,024 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 860 MHz. Complementing the processing units are 64 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The HD 7850 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 300 W to handle the GPU's thermal design power (TDP) of 130 W.
About the ATI Radeon HD 4870 (Mac Edition) GPU
The ATI Radeon HD 4870 (Mac Edition) is an end-of-life desktop graphics card that released in Q1 2009. It is built on the TeraScale GPU microarchitecture (codename RV770) and is manufactured on a 55 nm process.
Memory
The HD 4870 has 512 MB of GDDR5 memory, with a 850 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 108.8 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 4870 includes 800 shading units, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 750 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 4870 occupies 2 PCIe expansion slots. It supports DVI, mini-DisplayPort 1.0 display connections. ATI recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 150 W.
