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 523rd best 3DMark 11 Performance GPU score among the 566 benchmarked GPUs in our database. It achieves 0.48% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 5090. Its 623 score and $55 launch price (MSRP) gives it a performance per dollar of 11.33. This is the 106th best in value for the 3DMark 11 Performance GPU benchmark.

About the NVIDIA GeForce RTX 5090 GPU

The NVIDIA GeForce RTX 5090 is a desktop graphics card that launched in Q1 2025 with a MSRP of $1,999. It is built on the Blackwell 2.0 GPU microarchitecture (codename GB202) and is manufactured on a 5 nm process.

Memory

The RTX 5090 has 32 GB of GDDR7 memory, with a 1,750 MHz memory clock and a 512 bit interface. This gives it a memory bandwidth of 1.79 Tb/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 RTX 5090 includes 21,760 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,017 MHz and can dynamically boost its clock speed up to 2,407 MHz. Complementing the processing units are 680 texture mapping units (TMUs) for efficient texture filtering and 176 render output units (ROPs) for pixel processing. Additionally, the GPU features 680 tensor cores optimized for AI-accelerated workloads and 170 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RTX 5090 occupies 2 PCIe expansion slots. It supports HDMI 2.1b, DisplayPort 2.1b display connections. NVIDIA recommends a power supply of at least 950 W to handle the GPU's thermal design power (TDP) of 575 W.

Benchmark Performance & Value

The RTX 5090 has the best 3DMark 11 Performance GPU score among the 566 benchmarked GPUs in our database. Its 129,772 score and $1,999 launch price (MSRP) gives it a performance per dollar of 64.92. This is the 60th best in value for the 3DMark 11 Performance GPU benchmark.
