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 NVIDIA GeForce 845M GPU
The NVIDIA GeForce 845M is an end-of-life mobile graphics card that released in Q1 2015. It is built on the Maxwell GPU microarchitecture (codename GM107) and is manufactured on a 28 nm process.
Memory
The 845M has 2 GB of DDR3 memory, with a 1,001 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 16.02 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 845M includes 512 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 863 MHz and can dynamically boost its clock speed up to 863 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 45 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The 845M has the 303rd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.84% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
