NVIDIA RTX 4090 assessment: Unholy energy

How do you go about reviewing one thing like NVIDIA’s RTX 4090? Simply taking a look at its specs alone, it is clearly the quickest client GPU we have ever seen. So certain, I can inform you that I can play absolutely anything in 4K with ray tracing and each graphical nicety turned on. Hell, it may possibly even scale as much as 8K when you’re a masochist. For a $1,599 video card, it rattling effectively higher. However the actual query is, who is that this factor really for?

Benching the RTX 4090 towards NVIDIA and AMD’s older {hardware} is virtually pointless. In fact it is sooner. In fact it will make you jealous. For those who’ve received the money and also you’re itching to improve, go along with God (or NVIDIA’s leather-clad CEO Jensen Huang, as the corporate’s followers see him). However for anybody else who does not want bleeding edge {hardware}, it exists purely as an object of lust. Positive, you can await the upcoming RTX 4080 playing cards, or no matter AMD has within the works, however it’s not a 4090. Identical to the final era of GPUs, NVIDIA is throwing down the gauntlet with a power-hungry card for essentially the most hardcore avid gamers and creators.


  • Unimaginable efficiency
  • Environment friendly cooling
  • Viable 4K ray tracing


  • Large energy calls for
  • Requires 4 cables on older PSUs
  • Costly

In case your thoughts is not made up, I assume you are right here simply to see how a lot of a beast the 4090 is. And let me inform you, it is a beautiful factor to behold. Weighing in at 4.8 kilos, and approaching the dimensions of the PlayStation 5, the RTX 4090 is a triple-slot GPU that can dominate no matter case it’s in. Significantly, when you’re pondering of getting it, make sure to measure your PC to make sure you can match a virtually foot-long card that is shut to five inches thick.

Be ready to improve your energy provide too: The 4090 has a excessive 450W TDP (the identical thermal design profile because the 3090 Ti) and it requires an 850W PSU. (Some third-party firms are pushing that demand to 1200W PSUs!) Whereas it may be powered by a single PCIe 5.0 cable, there nonetheless aren’t a lot of these PSUs in the marketplace, so most individuals will doubtless find yourself utilizing 4 8-pin adapters. I cursed Jensen’s title after I realized I wanted to string one other PSU line, after tidying up all of my cables.

Past its obscene energy calls for, although, NVIDIA hasn’t modified a lot in regards to the 4090 Founder Version’s design from its earlier mannequin: It is nonetheless a high-end, all-metal card with an enormous vapor chamber, heatsink array and two followers on reverse sides. NVIDIA claims they will push 20 p.c extra air than the 3090 Ti – in my testing, that meant the 4090 stayed at a comparatively cool 70C below load.

What’s really particular in regards to the RTX 4090, although, is every thing below the hood. It options the corporate’s new “Ada Lovelace” structure (named after the world’s first laptop programmer, although I’m wondering if NVIDIA pays any royalties to show her title into advertising and marketing). It has 16,384 CUDA cores (virtually 6,000 greater than the 3090 Ti), a base clock velocity of two.23GHz (increase to 2.52GHz), and 24GB of GDDR6X RAM. With figures like these, the upcoming RTX 4080 playing cards (which begin with 7,680 CUDA cores) appear puny as compared.
