This very specific GTX 770 4GB versus GTX 770 2GB comparison is a follow up to our EVGA GTX 770 4GB review last week. It attempts to demonstrate the performance differences between a 4GB GTX 770 and a GTX 770 with 2GB at resolutions of 1920×1080, 2560×1600 and 5760×1080. We are going to compare two GTX 770′s clocked the same, and identical in every respect, except that one is equipped with 2GB whereas the other has 4GB of GDDR5. Above are pictured the EVGA GTX 770 that comes equipped with 4GB and the reference GTX 770 that comes standard equipped with 2GB. Both GTX 770s use the same GPU, and when clocks are set similarly, the performance is effectively identical as long as the framebuffer of the 2GB card is not exceeded.
EVGA GTX 770 4GB vs Nvidia GTX 770 2GB benchmarked
This particular evaluation is designed to compare 4GB vRAM versus 2GB. Since we do not want any chance of our CPU “bottlenecking” our graphics, we are testing our two graphics cards by using our Ivy Bridge Intel Core i7-3770K at 4.50GHz, 16GB Kingston “Beast” HyperX DDR3 at 2133MHz, and an EVGA Z77 FTW motherboard. The Core i7-3770K at 4.5GHz is more than enough to differentiate even high-end video cards at high resolution and at high detail settings.
The EVGA Z77 FTW motherboard features 16x + 16x PCIe 3.0 specification for CrossFire/SLI which we will test in the next article covering GTX 770 SLI as we have just received a 2GB GTX 770 Hall of Fame edition from Galaxy for evaluation. Unfortunately, we were unable to SLI our 4GB EVGA GTX 770 with the 2GB reference GTX 770 even using Coolbits, and we did not want to use older (modded) drivers.
The EVGA GTX 770 SC uses the same PCB as the reference version, but we note that it uses double capacity GDDR5 modules totaling 4GB instead of the standard 2GB. There is one interesting thing that we did not cover in our original evaluation of the EVGA GTX 770 SC. It has a dual-BIOS switch. We can’t wait to test out two GTX 770s against each other, but before we begin the testing, head over to our testing configuration.
