About the AMD Radeon HD 6450 GPU
The AMD Radeon HD 6450 is an end-of-life desktop graphics card that released in Q2 2011 with a MSRP of $55. It is built on the TeraScale 2 GPU microarchitecture (codename Caicos) and is manufactured on a 40 nm process.
Memory
The HD 6450 has 512 MB of DDR3, GDDR5 memory, with a 500 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 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 6450 includes 160 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 625 MHz. Complementing the processing units are 8 texture mapping units (TMUs) for efficient texture filtering and 4 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The HD 6450 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DVI, HDMI 1.3a, VGA display connections. AMD recommends a power supply of at least 200 W to handle the GPU's thermal design power (TDP) of 18 W.
Benchmark Performance & Value
The HD 6450 has the 500th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.60% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 623 score and $55 launch price (MSRP) gives it a performance per dollar of 11.33. This is the 96th best in value for the 3DMark 11 Performance GPU benchmark.
About the AMD Radeon HD 7970 GPU
The AMD Radeon HD 7970 is an end-of-life desktop graphics card that released in Q1 2012 with a MSRP of $549. It is built on the GCN 1.0 GPU microarchitecture (codename Tahiti) and is manufactured on a 28 nm process.
Memory
The HD 7970 has 3 GB of GDDR5 memory, with a 1,375 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 264 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 7970 includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 925 MHz. Complementing the processing units are 128 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The HD 7970 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 600 W to handle the GPU's thermal design power (TDP) of 250 W.
Benchmark Performance & Value
The HD 7970 has the 211th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 7.43% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 7,770 score and $549 launch price (MSRP) gives it a performance per dollar of 14.15. This is the 92nd best in value for the 3DMark 11 Performance GPU benchmark.
