About the AMD Radeon HD 6990M GPU
The AMD Radeon HD 6990M is an end-of-life mobile graphics card that released in Q3 2011. It is built on the TeraScale 2 GPU microarchitecture (codename Blackcomb) and is manufactured on a 40 nm process.
Memory
The HD 6990M has 2 GB of GDDR5 memory, with a 900 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 115.2 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 6990M includes 1,120 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 715 MHz. Complementing the processing units are 56 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.
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 HD 6990M has the 291st best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 3.09% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the NVIDIA GeForce GT 555M GPU
The NVIDIA GeForce GT 555M is an end-of-life mobile graphics card that released in Q4 2011. It is built on the Fermi GPU microarchitecture (codename GF106) and is manufactured on a 40 nm process.
Memory
The GT 555M has 1,024 MB of DDR3 memory, with a 900 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 28.8 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 GT 555M includes 144 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 525 MHz and can dynamically boost its clock speed up to 753 MHz. Complementing the processing units are 24 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 35 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 555M has the 440th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.10% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
