GeForce RTX 3090 vs GeForce GTX 750 benchmarks

According to the hardwareDB Benchmark, the GeForce RTX 3090 GPU is faster than the GeForce GTX 750 in gaming.

In our comparison, the GeForce RTX 3090 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the GeForce RTX 3090 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the GeForce RTX 3090 has significantly more memory with 24 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 750 has a significantly lower TDP at 55 W when compared to the GeForce RTX 3090 at 350 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 3090 over the GeForce GTX 750.
