Asus RTX 4090 ROG Strix OC review: Really big | Whuff News

The Nvidia GeForce RTX 4090 launched last week, setting a new bar high for the competition to clear. With the RTX 4090 being on top GPU benchmark hierarchy and ranked as the fastest best graphics card, there are still questions about which specific 4090 model you should buy. In addition to the Founders Edition, we have cards from various third-party add-on board (AIB) partners on the way. We start our third party reviews with Asus RTX 4090 ROG Strix OC (opens in new tab)a very large card that dwarfs the already fat 4090 Founders Edition.

The simple answer to which card you should buy is “whatever RTX 4090 you can find in stock.” Despite the extreme price, the performance improvement was significant enough that all 4090 cards nearly sold out at launch. Of course some of that can be attributed to Scalper RTX 4090but without cryptocurrency GPU mining — no, the RTX 4090 is not profitable for mining, nor are other GPUs right now — we can only hope that the scalper prices will disappear quickly.

That naturally depends on Nvidia getting a sufficient supply of RTX 4090 GPUs to market. Even though we know the cards are sold out, we don’t know how many cards have been sold actually sold. It could be thousands, or maybe even tens of thousands. But halo GPU launches don’t usually come with mass supplies. Still, the RTX 4090 is very fast and Nvidia may not be in a rush to push another 40-series model — not when Nvidia by its own admission (opens in new tab) said it expects to be in an oversupplied situation at least by the end of the year.

Nvidia can’t delay forever, however, not with AMD announced RDNA 3 on November 3rd. We fully expect AMD to offer some cards — perhaps the Radeon RX 7900 XT — at a much lower price than the RTX 4090. There may also be multiple high-end cards using Navi 31, such as the RX 7950 XT, RX 7900 XT, and RX 7800 XT. We’ll know more in the coming weeks.

We’ve now tested three different RTX 4090 cards: the Founder’s Edition, this Asus ROG Strix and (review to come) the MSI Suprim Liquid X. We’ll have results for all three cards in this review, although knowledgeable gamers will know that performance is rare differ significantly between cards using the same core GPU — aesthetics and other factors become more important. Here are the specs for the three different ones

We’ve removed most of the redundant lines from the specs list above, as all three cards have the same basic hardware. The only real difference in terms of specs comes from the boost clock and any potential difference in power rating.

Asus didn’t specify TBP, although we suspect it’s the same 450W as the Founder’s Edition. If you install Asus GPU Tweak, you can also select OC mode which uses an extra 30 MHz on the GPU core clock and increases the power limit by a few percent. We’re skipping that and will instead investigate manual overclocking.

On paper, the Asus card has 3.6% factory overclock while the MSI card has 4.2% factory overclock. In practice, the GPU clocks we measured during testing were much closer than that. The Founders Edition averaged 2738 MHz in our Metro Exodus test, the MSI card got 2783 MHz (1.6% higher), and the Asus card got 2791 MHz (1.9% higher). As always, Nvidia’s real-world GPU clocks tend to easily beat the spec sheet.

We also ran some additional tests on the RTX 4090 Founders Edition, including professional content creation workloads and DLSS 3 tests. For our AIB card review, given the relatively limited differences we saw in performance, we’ll focus more on the card’s design and aesthetics as well as any other additions.
