NVIDIA quietly released a variant of the GeForce RTX 4070 featuring slower 20 Gbps GDDR6 memory, replacing the 21 Gbps GDDR6X that the original RTX 4070 comes with. Wccftech has access to a GALAX branded RTX 4070 GDDR6, and put it through benchmarks focused on comparing it to a regular RTX 4070. Memory type and speed are the only changes in specs, the core-configuration isn't changed, nor is the GPU clock speed. Wccftech's testing shows that the RTX 4070 GDDR6 measures within 0-1% slower than the RTX 4070 (GDDR6X) at 1080p and 1440p resolutions; while the difference between the two is about 2% at 4K Ultra HD.
