![]() ![]() However, we've enabled XMP memory profiles for our GPU testbed, which seems to narrow the gap quite a bit, particularly with the RTX 3070. The Core i9-10900K and Ryzen 9 5900X may be slightly faster, depending on the game used and other settings. Our test PC is the same Intel Core i9-9900K we've been using for over a year now, with full details to the right. We didn't run the same overclocking tests on the Founders Edition back when we first tested it, but in the tests that we did run, we saw performance slightly higher than the Asus card gets using the OC Mode. We've included both 'stock' (using the OC Mode) results and performance running our maximum manual overclock in the charts (we didn't run benchmarks using the Gaming Mode or Silent Mode). We've only tested one custom 3070 so far, which we'll highlight in bright red, with the reference 3070 Founders Edition in a darker shade. Asus RTX 3070 TUF Gaming: 1080p Gaming Performance Redlining a card for an extra 5% performance isn't really a great idea, but YMMV. If you run one of these cards with the fans usually spinning at 50-75%, the bearings are likely to wear out quicker, and we feel you're better off just sticking with the default OC Mode for long-term use. In other words, we consider our OC’d results to be closer to the maximum you should expect to achieve, and we're being aggressive on fan speeds to get there. We also ramped up fan speeds quite a bit - using the stock fan profile, we could only get around 50 MHz extra on the GPU core and a 600 MHz memory overclock. We maxed out the power limit and managed to add 750 MHz to the GDDR6 base clock (15.5Gbps effective speed), but we could only add 75 MHz to the GPU core clocks before we encountered instability. ![]() We also did some manual overclocking, which showed similar results to what we've seen with other Ampere GPUs. We used GPU Tweak II during testing, setting it to OC Mode. Our testing (see below) generally confirms these claims. Asus also rotates the center fan clockwise, with the side fans spinning counterclockwise, which it says reduces turbulence and noise. Considering we saw very good results from the cooling on the higher power RTX 3080 TUF, the fans should be more than sufficient for the 3070 card. The 3070 TUF has three 90mm fans, and they're the new style with an integrated rim that increases static pressure and helps improve airflow at the same RPM. Naturally, the Strix models cost more than the TUF models, with slightly higher factory overclocks and better cooling in addition to the extra RGB lighting. TUF is the more mainstream approach to design and aesthetics. If you're after more bling, Asus has the Strix line for that. The TUF logo on the top of the card lights up, and there's a small RGB strip on the front edge of the card (linked to the same lights as the logo), and that's it. RGB lighting is present, but it's very tame compared to other GPUs. Based on our power testing, it will be challenging to push the card beyond 300W, and an 8-pin plus 6-pin setup would have been sufficient, but it was probably easier to just keep the dual 8-pin connections used on other models. The 3070 TUF still requires dual 8-pin power connectors, just like the 30 variants, which is a bit interesting to see. ![]() While the reference 3070 has an official TGP (Total Graphics Power) of 220W, Asus doesn't explicitly list a TGP and instead recommends at least a 750W power supply. However, you can only use the OC Mode if you install the Asus GPU Tweak II software (see below) - otherwise, you'll get the slightly lower Gaming Mode clocks. The OC Mode has a boost clock of 1845 MHz, compared to 1815 MHz in the default Gaming mode, and 1785 MHz in Quiet Mode. A switch on the top of the card can toggle between 'quiet' and 'performance' modes (reboot required), but that's not the full story.
