NVLink support has disappeared on the RTX 4000

As many of you may know, NVLink is Nvidia's proprietary technology for interconnecting two video cards. This is the direct evolution of SLI (Scalable Link Interface), launched in 2005, which, unlike the latter, allows bidirectional bandwidth up to 50GB / s. However, the ever-increasing increase in power in recent GPUs has made the use of a dual video card configuration superfluous, relegating it more and more to professional systems, such as workstations. This is probably the reason that prompted the company to remove its support on Ada Lovelace, as directly confirmed by Jensen Huang.

In an interview with the press, the CEO explained that the connector is absent on the new GeForce RTX 4000 presented a few days ago, which marks the end of multi-GPU configurations. Motivating the decision, Jensen said there was a need to use its I / O for "something else". The engineers also wanted to make the most of the area in order to dedicate as much of it as possible to the AI ​​processing units.

“Ada Lovelace does not support PCIe Gen 5, but the Gen 5 power connector is included. PCIe Gen 4 now offers a lot of bandwidth for graphics usage, so we felt it wasn't necessary to implement PCI-E Gen 5 for this generation of graphics cards. The large framebuffers and the large L2 cache of the Ada GPUs also reduce the use of the PCIe interface. "

At the GTC 2022 event, the company unveiled the first top-of-the-range models of the new series, namely GeForce RTX 4090 and RTX 4080 (the latter available in two variants of 12GB or 16GB).

Mystery Nvidia RTX 4000 GPU features twice the power of RTX 3000

09/09/2022 The source for this story confirms their claim is bogus, but synthetic benchmark leaks show that they might not be far off the real deal. As always, we recommend treading lightly when it comes to rumours and leaks, as they rarely paint the full picture.

Nvidia RTX 4000 GPUs will undoubtedly fight for the best graphics card crown, leaked benchmarks suggest one will feature twice the power compared to RTX 3000. Better still, the comparison is seemingly based on 4K gameplay, but it’s not clear which mystery SKU the insider figures belong to.

According to QbitLeaks on Twitter, one of the upcoming Nvidia RTX 4000 graphics cards will double the performance of RTX 3000 in games like Control, Cyberpunk 2077, and Dying Light 2. The leaker says the benchmarks don’t belong to a flagship card, like the RTX 4090, meaning we’re potentially looking at RTX 4080 or RTX 4070 performance stats.

If anything, the RTX 4000 leaked benchmarks add clout to previous performance claims. Earlier whispers hint that the RTX 4070 will pack an RTX 3090 Ti punch, and RTX 4080 insider info points towards a 60-80% increase.

QbitLeaks also says they “don’t think” Nvidia DLSS was used during the RTX 4000 benchmark, something that makes the feat all the more impressive. Provided the stats actually reflect true next-gen GPU performance, players could boost fps higher than ever before by opting to use the RTX AI upscaler, enabling rigs to run games at 4K with fewer settings caveats.

Before you start planning to replace a card like the MSI RTX 3090 Suprim X with an entry-level RTX 4000 card, we’d recommend taking the benchmark with the usual grain of salt. Nvidia hasn’t made any official announcements as of yet, and the company is seemingly struggling to make its mind up about RTX 4070 specs.

That said, RTX 4000 will likely take the best gaming PC setup to new heights, and enthusiasts may have a large selection of SKUs to choose from. Nvidia is apparently toying with releasing two RTX 4080 models at the same time, and there’s already talk of souped-up cards like the RTX 4070 Ti and RTX 4090 Ti.

Word of an RTX 4000 delay means we might need to wait till after Halloween to see what the green team truly has up its sleeve, but that’s perhaps a short wait for anyone who’s been trying to get a hold of any GPU for the past two years.
