Nvidia GeForce RTX 4080 review: Second only to the 4090—for now

Little or no about Nvidia’s GeForce RTX 4080 is shocking—particularly now that the confusing, scrapped 12GB version is being renamed. In just about all of our efficiency exams, it slots in proper the place you’d anticipate it to, comfortably forward of the RTX 3080 Ti however trailing the $1,500 RTX 4090 by sufficient to justify the $300 value hole. It is normally able to hitting or exceeding 60 fps at 4K, and video games with DLSS assist (or another type of upscaling tech) should buy you a stable body charge enhance. And its energy necessities aren’t as stratospheric because the 4090’s, both, so most individuals with an current xx70 or xx80-class gaming PC should not want to modify out their energy provide.

The foremost downsides, as of this writing? As a bunch, the playing cards are sometimes simply as large and cumbersome because the RTX 4090 (the Founders Version is similar, and companion playing cards largely observe go well with). The $1,200 beginning value is traditionally excessive—the 3080 Ti launched with a GPU-shortage-inflated MSRP of $1,119 GPU, however the 2080 and 3080 had been each a mere $699 at launch. And even for those who are prepared to pay that value—shock, shock—it is mainly inconceivable to seek out in any kind wherever near MSRP.

Which implies, hooray: one other GPU assessment that exists principally as a theoretical train! If you might purchase this GPU for the sum of money it is speculated to price, and if its opponents had been additionally obtainable for what they had been speculated to price, then this is how it might stack up. That world does not exist proper now, however for those who’re studying this in a couple of months, circumstances could have modified. Within the meantime, think about with us, will not you?

Concerning the dimension—and that energy connector

The 4080’s bodily dimensions are 12.3×5.35×2.13 inches, similar because the 4090, and our 4090 assessment has a number of pictures evaluating it to numerous objects so you may get an concept of simply how giant that’s. It is a GPU that is roughly the identical dimension as a complete Xbox Collection S.

That does have ramifications for upgraders, significantly these utilizing extra space-efficient circumstances. Loads of gaming-focused mini ITX circumstances will not match a 4090 or 4080 in any respect, and though the case I exploit for my testbed suits full-size ATX motherboards (a Lian Li O11 Air Mini), I am unable to put the facet panel again on with the cardboard put in as a result of the included energy adapter stands out an excessive amount of. When you issue within the front-mounted radiator and tubing for the CPU cooler, it is a tight match, and it is one thing to bear in mind when upgrading an current PC moderately than constructing a brand new PC particularly designed to accommodate the cardboard.

With regards to that energy adapter, the 4080 nonetheless makes use of a 12VHPWR energy connector, the identical because the RTX 4090—the adapter simply desires three 8-pin energy adapters plugged into it as a substitute of 4. This connector has been the topic of some controversy due to overheating and melting issues that some users have experienced. The dangerous information is that the 4080’s adapter is probably going inclined to the identical challenge, however the excellent news is that, most often, Nvidia and third-party testers have discovered that this overheating is created when the cables aren’t fairly plugged in all the best way, one thing most individuals ought to have the ability to keep away from with slightly care.

One of the simplest ways to examine the firmness of your connection is to offer the adapter a few agency tugs to verify it does not come unseated—it might pull again a millimeter or two when you’re doing this however not sufficient to trigger the warmth issues that some folks have been seeing. Push the connector again down after you’ve got accomplished this and attempt to watch out to not pull the cables round an excessive amount of or bend them at an excessive angle.

By way of energy draw, the Founders Version of the RTX 4080 is rated at round 320 W, the identical because the last-generation RTX 3080 and decrease than the 4090 (450 W) and the 3080 Ti (350 W). In observe, we discovered it to be even higher behaved, drawing a mean of just below 300 W throughout a Hitman 3 benchmark run and averaging a comparatively cool 59.8 levels Celsius. The hulking heatsink and followers are overkill, however they do their job. Nvidia recommends a 750 W energy provide, the identical because the RTX 3080 and 3080 Ti, and also you would possibly have the ability to get away with much less for those who’ve paired it with a modest 6- or 8-core CPU.
