GDDR6 GeForce RTX 4070 Tested, Loses 0-1% Performance Against RTX 4070 with GDDR6X
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.
Wccftech's test-bed is comprehensive, with 27 game tests, each across 3 resolutions; and 7 synthetic tests. The synthetic tests are mainly part of the 3DMark test suite, including Speed Way, Fire Strike, Time Spy, Port Royal, and their presets. Here, the RTX 4070 GDDR6 is nearly identical in performance, with a 0-0.2% delta with the RTX 4070 GDDR6X. In the game tests, performance varies by resolution. 1080p has 0-1% performance delta, with the only noteworthy outliers being "Metro Exodus" (extreme preset), where the RTX 4070 GDDR6 loses 4.2%, and "Alan Wake 2," where it loses 2.3%.
