GeForce GTX 1070 vs GeForce RTX 3070 benchmarks
In our benchmarks, the GeForce RTX 3070 beats the GeForce GTX 1070 in gaming performance.
Our database shows that the GeForce GTX 1070 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. Despite this, the GeForce RTX 3070 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 they both have the same amount of memory at 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.
In addition, the GeForce GTX 1070 has a significantly lower TDP at 150 W when compared to the GeForce RTX 3070 at 220 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 3070 over the GeForce GTX 1070.
