Siggraph 2023: Nvidia announces RTX 5000, 4500 and 4000 with Ada graphics chip

Nvidia’s current graphics chips of the Ada Lovelace generation have so far mainly been used on gaming graphics cards from the GeForce RTX 4000 series with their latest offspring, the RTX 4060. The largest Ada chip came on the workstation graphics cards in the RTX series AD102 has so far only been used in the top model RTX 6000 Ada with 48 GB, Nvidia continues to equip cheaper models with the graphics chips from the previous generation “Ampere”.

During the opening speech at this year’s Siggraph, Nvidia boss Jen-Hsun Huang presented three more RTX Ada cards, which should also bring the new technology into price segments below around 9400 euros for the RTX 6000 Ada. The Nvidia RTX 5000 Ada with 32 GB, the RTX 4500 Ada with 24 GB and the RTX 4000 Ada with 20 GB graphics memory. They not only succeed the RTX Ampere series, i.e. RTX A5000 & Co., but also have to assert themselves against AMD’s Radeon Pro W7000, four variants of which have been released so far, including the inexpensive Radeon Pro W7600 and W7500.

High processing power and efficiency, slower memory

Nvidia states that the cards are 50 to 100 percent faster in classic graphics, AI and rendering applications compared to their respective numerical predecessors with Ampere GPUs. In the Omniverse environment, which also receives DLSS 3 frame generation with an update, they should be up to three times as fast.

Even if they carry 20 to 33 percent more memory, the new ones have to cut back on the memory transfer rate. The RTX 5000 Ada has a transfer rate that is a quarter lower than the RTX A5000 with an Ampere GPU (576 to 768 GB/s), with the 4500s it is minus 32.5 percent and with the 4000 models it is 20 percent less. As with the GeForce gaming graphics cards, Nvidia would like to intercept this with the significantly larger level 2 cache of the Ada chips – which has worked well in games so far.

The new RTX 5000 Ada is said to cost around $4000 excluding taxes. This places it in the range of AMD’s Radeon Pro W7900, which, however, has 48 instead of just 32 GB. The RTX 4500 Ada comes with 24 GB for around 2250 US dollars plus taxes and has to compete against AMD’s Radeon Pro W7800 with 32 GB. These two RTX cards have their dual-slot cooler and consume a nominal 250 and 210 watts respectively, making them a bit more economical than the AMD counterparts. Compared to their own predecessors, the cards are 20 (RTX 5000 Ada) or 10 watts (RTX 4500 Ada) thirstier.

The RTX 4000 Ada is a significantly slimmed down version of the RTX 4500 Ada, whose TDP has been trimmed down to 130 watts, i.e. around 62 percent compared to the 4500 Ada. This value is enough to screw a single-slot cooler onto it, like the much cheaper Radeon Pro W7600, which also works much more slowly. Compared to the Nvidia RTX A4000 from the previous generation, this is 10 watts less.

All new RTX Ada cards have the new 16-pin connector of the ATX 3.0 specification. There are four full-size DisplayPorts of version 1.4a in the slots. This is sufficient (each) for 4K with 120 Hz and DSC, 5K with 60 Hz and DSC or for a total of two times 8K60 with DSC. Combinations such as 4 × 5K (60 Hz), 2 × 8K (60 Hz) or 1 × 12K (120 Hz with DSC) are reserved for the Radeon Pro W7800/7900 with their DP2.1 connections.

The Nvidia RTX 5000 Ada is said to be available now, followed by the RTX 4000 Ada in September and the RTX 4500 Ada in October. Unlike their predecessors, the new cards no longer support coupling via NVLink.
