GeForce RTX 4090 vs GeForce RTX 4080 specs and performance

For gaming, the GeForce RTX 4090 graphics card is better than the GeForce RTX 4080 in our tests.

The GeForce RTX 4090 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 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 4090 has significantly more memory with 24 GiB of memory compared to 16 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce RTX 4080 has a slightly lower TDP at 420 W when compared to the GeForce RTX 4090 at 450 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 4090 is faster than the GeForce RTX 4080.
