There’s going to be lots of criticism aimed toward Nvidia’s new RTX 4080 nevertheless it’s vital to emphasize that there’s nothing fallacious with the Founders Version we’re reviewing right this moment by way of its development, options and general high quality. Similar to the RTX 4090, it is a high quality product created by an organization that is arguably on the high of its recreation, a agency on the pioneering forefront of graphics know-how. Pricing is a unique matter, nonetheless. It is just too excessive, even at its MSRP baseline and particularly so with a number of the third get together associate playing cards we have seen. The product is an effective chunk sooner than any of the prior Nvidia Ampere choices, together with the RTX 3090 Ti, however the efficiency increase would not at all times correlate with the value being charged, to the purpose the place there are knowledge factors to counsel that the $1599 RTX 4090 truly provides a greater deal.

The Founders Version we’re right this moment arrives in the identical packaging because the RTX 4090 and in the identical glorious casing. The one distinction is that whereas the identical controversial 12VHPWR socket is on the cardboard (sure, the melting one – and we’re nonetheless ready for definitive solutions on why that occurred) however this time you get a dongle adapter with simply three eight-pin PCIe inputs. That is nonetheless greater than sufficient, making an allowance for that the far more power-hungry RTX 3090 Ti shipped with the identical adapter – and the RTX 4090 labored with it too. The uniform design throughout each Ada Lovelace playing cards additionally implies that you are getting the identical video choices: one HDMI 2.1 and three DisplayPort 1.4a ports.

Nvidia GeForce RTX 4080 – the Digital Foundry video overview.

As it is a new era of GPU, there are a sure suite of options widespread to each RTX 4090 and RTX 4080 – regardless that they’re utilizing completely separate chips. Because of this the improved video encoding choices of Ada Lovelace are preserved – a lot sooner h.264/HEVC encoding, together with twin AV1 encoders. After the RTX 4090 overview, we took a take a look at the AV1 performance – and it is spectacular. For our prime quality video downloads on digitalfoundry.internet, we discovered that AV1 {hardware} encoding delivered larger high quality than software-based h.264 with a giant file measurement saving and whereas software-based HEVC encoding delivered smaller information, Nvidia AV1 provided up larger high quality. For streamers and content material creators, RTX 4000 is a giant deal. Options like this could persist throughout all RTX 4000 merchandise as newer and cheaper playing cards emerge.

Within the desk beneath, you will see how the RTX 4080 compares to its flagship associate and it is honest to say that the cutbacks are huge – wider and deeper than the specs differential we noticed between RTX 3090 and RTX 3080. You are getting round 59 % of the compute energy, 73 % of the reminiscence bandwidth and two thirds of the VRAM. And but, you are paying 74 % of the associated fee worth of the flagship so realistically you have to be anticipating not less than 74 % of the RTX 4090’s efficiency. Ideally it needs to be much more, as customers anticipate a greater worth vs efficiency ratio the cheaper the product will get.

You will be aware that the desk above accommodates knowledge for the ‘cancelled’ RTX 4080 12GB, based mostly on a completely completely different Ada Lovelace processor and initially set to go on sale for $899. Its cancellation is definitely extra of a delay as the cardboard will get rebranded into a unique product line (our cash remains to be on RTX 4070 Ti) and is hotly rumoured to be arriving in early January.

Earlier than we transfer on to the battery of recreation efficiency assessments we now have put collectively, let’s take a fast take a look at energy effectivity. Going into this era of graphics {hardware}, we have been gearing up for very power-hungry units set to reach in the midst of an vitality disaster – not a good suggestion, maybe. Inaccurate rumours of a 900W RTX 4090 gave technique to a 600W RTX 4090 and at last, the precise TGP: 450W. That is nonetheless lots of energy, however precise in-game utilization is decrease. The facility restrict of the RTX 4080 is 320W, so on this regard it’s precisely the identical as its predecessor, however what is the actuality in gaming?

Vitality effectivity varies drastically in accordance with the sport you might be operating, after all, if we stack up efficiency towards energy consumed – which is strictly what we have completed within the desk beneath. In all instances, the RTX 4080 stories energy consumption beneath its 320W restrict and in contrast towards prior 80-class playing cards, there are sizeable effectivity benefits. Put merely, frame-rates are considerably improved gen-on-gen and particularly towards RTX 3080, the efficiency benefit would not end in a lot of the way in which in elevated consumption. The truth is, as you will see beneath, the RTX 4080 can ship each a efficiency increase and a discount in energy consumption concurrently in some workloads.

GeForce RTX 2080 GeForce RTX 3080 GeForce RTX 4080 Per Body Energy Discount
Management, 4K, Excessive RT 213W/17.2fps – 12.38 Joules Per Body 309W/31.6fps – 9.78 Joules Per Body 301W/44.66fps – 6.74 Joules Per Body 45% vs 2080/ 31% vs 3080
Dying Gentle 2, 4K, Extremely RT 193W/11.23fps – 17.19 Joules Per Body 311W/25.3fps – 12.29 Joules Per Body 290W/38.6fps – 7.51 Joules Per Body 56% vs 2080/ 39% vs 3080
Forza Horizon 5, 4K, Excessive 181W/47.7fps – 3.79 Joules Per Body 290W/77.5fps – 3.74 Joules Per Body 217W/118.0fps – 1.84 Joules Per Body 52% vs 2080/ 51% vs 3080

All of which units the stage for a frankly colossal vary of benchmarks laid out over the following six pages, masking customary rasterisation in fashionable titles, a number of the most demanding ray tracing workloads we may put these playing cards by way of – plus a take a look at how right this moment’s picture reconstruction methods (DLSS, FSR2) may help to mitigate the efficiency impression of probably the most difficult video games.

Earlier than we kick off with the numbers, this is a fast define of the brand new PC we have constructed to assist take a look at this new era of GPUs. Sitting on the coronary heart of our system is an Intel Core i9 12900K, operating with P-cores at 5.2GHz and E-cores at 3.9GHz. The CPU is augmented with 6000MT/s Trident Z5 RGB DDR5 reminiscence from G-Ability. The Noctua NH-D15 is our cooler of selection for dealing with the highly effective processor, whereas all titles are run from PCIe Gen 3 NVMe SSDs. All elements are mounted in an Asus ROG Maximus Hero Z690 motherboard, whereas energy is provided by a Corsair RM1000i energy provide.

With the preliminaries out of the way in which, take a look at the desk of contents beneath and take a look at how the RTX 4080 compares towards its nearest Nvidia rivals, together with AMD’s RX 6900 XT and RX 6800 XT. Please be aware that within the wake of the RTX 4090 launch, Nvidia truly improved RTX 3000-class efficiency by way of a driver replace. All RTX playing cards have been re-benched to account for the adjustments in efficiency.
