The NVIDIA GeForce RTX 2070 Founders Edition Review: Mid-Range Turing, High-End Price
by Nate Oh on October 16, 2018 9:00 AM ESTOverclocking
Last, but not least, we'll take a look at overclocking. While NVIDIA does support overclocking, they have limited actual overvolting, and instead providing the ability to unlock 1-2 more boost bins and associated voltages. Either way, Maxwell 2 and Pascal certainly have much to thank for high clockspeeds; for Maxwell 2, it was a combination of high efficiency and ample overclocking headroom, while Pascal took advantage of the FinFET process to ramp up the clocks to new heights.
Built on the 12nm "FFN" process, Turing doesn't appear to push the envelope spec-wise, although it does introduce GPU Boost 4 and NVIDIA Scanner, both of which are naturally featured in EVGA's Precision tool. Re-designed into the RTX-oriented Precision X1, the utility succeeds Precision XOC, and we've opted to use that tool for our overclocking today. We adjusted the core and memory clocks, as well as the power/temperature limit and percent 'overvoltage.' For the 185W RTX 2070 Founders Edition, this is a 116% TDP limit (215W). We were unable to fully test the new Scanner functionality as it would not save to a profile and crashed on certain button presses, which is somewhat unsurprising given that Precision X1 is still in beta. But as far as NVIDIA's GPU Boost 4 is concerned, it exposes certain boost algorithms to users so that you can manually modify the voltage-frequency curve.
A total of four different overclocks were tested. First was a baseline, consisting of 100% overvoltage and max power/temperature limits. The second was overclocking the GDDR6 memory by 1Gbps. The third was overclocking the GPU by +100MHz; in practice this resulted in observed clocks between 1900 and 1990 MHz. Lastly, all previous adjustments were combined for an overall overclock.
| RTX 2070 Founders Edition Overclocking | |||||||
| Stock (FE) | Baseline | Memory OC | GPU OC | All OC | |||
| Core Clock | 1410MHz | 1410MHz | 1410MHz | 1510MHz | 1510MHz | ||
| Boost Clock | 1710MHz | 1710MHz | 1710MHz | 1810MHz | 1810MHz | ||
| Max Boost Clock | 2160MHz | 2160MHz | 2160MHz | 2160MHz | 2160MHz | ||
| Memory Clock | 14Gbps | 14Gbps | 15Gbps | 14Gbps | 15Gbps | ||
| Max Voltage | 1.050v | 1.087v | 1.087v | 1.087v | 1.087v | ||
| Power Limit | 185W (100%) | 215W (116%) | 215W (116%) | 215W (116%) | 215W (116%) | ||
Naturally, these results cannot be taken as representative of all RTX 2070 Founders Edition cards, but results here can offer some insight.
Although this is more of a cursory look than anything else, the combined overclock provides the best performance, just like it was for the Pascal based cards like the GTX 1080 and 1070. Given the GDDR6-equipped 2070, we would expect memory overclocking to be less effective, though it appears it's necessary for the best overclock here. Ultimately, the combined overclock can make up some ground, but the extent of its benefits are largely comparable to Pascal cards.
OC Power, Temperature, and Noise
There isn't much to add on the power, temperature, and noise front. The card will heats up a few more degrees, but kept relatively quiet thanks to its open air cooler. The full OC costs about ~30W at the wall in games, bringing it up to 1080 Ti FE levels, though only select games will see an overclocked RTX 2070 surpass the 1080 Ti.

Thanks for the review, nice as always.Was hoping to upgrade my 970 before Turing was announced, but I feel like I'm getting ripped of with these cards. The review did nothing to change that feeling, but that was to be expected.

Please investigate why Turing is slower than Volta for HGEMM. If it was using the tensor cores they should be not that slow.SMOGZINN - Tuesday, October 16, 2018 - link
On the "The Test" page you show that the "NVIDIA GeForce GTX 1070 Ti Founders Edition" is one of the cards being compared, but it does not show up in the benches.Targon - Tuesday, October 16, 2018 - link
From the information, seeing Vega 64 going up to a temp of 86C would put it into thermal throttle range, which would cripple performance. From my own experience, manually adjusting the fan settings in Global Wattman to go up to 4500rpm and with a temperature target of 75C will avoid the throttle issues in the first place and also improving performance significantly, even without tweaking clock speeds or voltages.So, if Vega 64 is getting throttled and still hitting the numbers reported, that implies that with the fan profile adjusted as I suggested, we would be seeing Vega 64 doing a bit better in terms of framerates.

Let's be honest: Vega isn't here for competition purposes, it's just included as a courtesy.atl - Tuesday, October 16, 2018 - link
Would be good to have some SLI & Cryptocurrency benchmarks includedTEAMSWITCHER - Tuesday, October 16, 2018 - link
These RTX cards are going to be a fantastic value......next summer when they drop the prices.

Even there, I don`t know if Navi can really be a 250$ GPU with 1080 GTX performances.sandman74 - Tuesday, October 16, 2018 - link
980 owner here gaming at 1440p. Really wanted to upgrade but when I cost everything up, PC gaming has suddenly become a very expensive hobby.Decided to completely abandon the PC as a future gaming platform mostly thanks to the pricing of the new gpu cards.
2.5yrs since the 1080 for barely better performance. RTX isn’t viable on this card. My own view is the new line up sucks.
Practically all my mates are on consoles these days which is a shame but it’s a sign of the times. Tried the BF5 beta on my xbox one S and was blown away at how decent it was. Had real fun playing with friends which is what matters.
So I can only imagine it’s even better on the Xbox One X which you can buy for the price of just this GPU.
Prices have gone insane, so I’m stepping out. Total respect for those that can justify the prices and carry on PC gaming. I can’t.

tl;dr rather get a heavily discounted 1080 Ti (which will probably be factory overclocked and have a beefier cooler).
