GeForce RTX 4080 vs GeForce RTX 4090 D comparison

According to the hardwareDB Benchmark, the GeForce RTX 4090 D GPU is faster than the GeForce RTX 4080 in gaming.

In our comparison, the GeForce RTX 4090 D has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the GeForce RTX 4090 D also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 4090 D has significantly more memory with 24 GiB of memory compared to 16 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the GeForce RTX 4080 has a slightly lower TDP at 420 W when compared to the GeForce RTX 4090 D at 425 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 4090 D over the GeForce RTX 4080.
