Meet Blackwell, Nvidia’s next-generation GPU architecture

Nvidia introducing its Blackwell GPU architecture at GTC 2024.

We finally have our first taste of Nvidia’s next generation of GPUs, named Blackwell. Sure, they’re built for enterprises, and no, they won’t run Cyberpunk 2077 (at least not officially). But this is the first look we’ve have at what Nvidia is cooking up for its RTX 50-series GPUs, which are rumored to launched sometime in the next year.

The GPU we have today is the B200 — Blackwell 200, if you can spot it — that comes packed with 208 billion transistors. The architecture is built on TSMC’s 4NP node, which is an enhanced version of the 5nm node. It’s a little surprising given that Nvidia’s Ada Lovelace GPUs are built with TSMC’s 4N node — one refinement step away from 4NP. Nvidia notes that it’s using a custom version of this process, however.

Nvidia laid out six parameters that set Blackwell apart. The first is that custom 4NP process, which Nvidia is using to connect two GPU dies across a 10TB-per-second interconnect. Second is an updated Transformer Engine. Nvidia says the architecture can handle double the model size of last-gen Ada Lovelace, and it supports a new 4-bit floating point instruction set.

There’s also fifth-generation NVLink, allowing enterprises to hook up Blackwell GPUs in sizes of 576 GPUs in a single fleet. Nvidia is throwing in a couple of AI security features as well, including confidential computing capabilities and a RAS (reliability, availability, and serviceability) engine to ensure maximum uptime for its data center GPU.

That’s great if you’re running a data center, but it’s the sixth and final pillar that gets me excited. Nvidia says the B200 has a dedicated decompression engine. This is focused on enterprise right now, but we’ve seen how big of a difference dedicated decompression hardware can make in gaming as well. If Nvidia carries this engine over to its gaming GPUs, and supports the proper formats, it could make a massive difference once you’re able to throw a Blackwell graphics card in your gaming PC.

All eyes are on the end of the year, or potentially early next year, for Nvidia’ Blackwell gaming GPUs to show up. For now, enterprise customers have access to the B200 through the HGX B200 — a server board that combines eight B200 GPUs — and the GB200, which brings together the B200 GPU with Nvidia’s Grace CPU. Nvidia is offering that part through the GB200 NVL72, which brings together a dizzying 72 B200 GPUs and 36 Grace CPUs.

I’ve reviewed every AMD and Nvidia GPU this generation — here’s how the two companies stack up
Three graphics cards on a gray background.

Nvidia and AMD make the best graphics cards you can buy, but choosing between them isn't easy. Unlike previous generations, AMD and Nvidia trade blows point-for-point in 2024, and picking a brand to go with isn't as easy as counting the dollars in your wallet.

I've reviewed every graphics card AMD and Nvidia have released this generation, comparing not only raw performance, but also features like DLSS and FSR, ray tracing performance, and how VRAM works in modern games. After dozens of graphics card reviews, here's how AMD and Nvidia stack up against each other in 2024.

Nvidia just dropped a big hint about the RTX 50-series release date
nvidia rtx 4080 review 12

Speculation has been running rampant about Nvidia's launch of next-gen RTX 50-series GPUs, but the company itself just dropped a big hint about when they may show up. Nvidia CEO Jensen Huang is set to take the stage as the keynote speaker of CES 2025 on January 6, where there's a good chance we'll hear about Nvidia's next generation of graphics cards.

Although Nvidia is at the annual tech show each year, Huang -- who recently surpassed the worth of all of Intel -- hasn't made an appearance in five years. The executive will likely focus heavily on AI, as it has catapulted Nvidia to become one of the world's wealthiest companies. But RTX 50-series GPUs should make an appearance, too. Nvidia usually takes advantage of CES to launch new graphics cards.

Prime Day is the perfect time to ditch Nvidia for AMD

There's no doubt that Nvidia makes some of the best graphics cards you can buy, but if you're shopping Prime Day deals, you'll want to take a careful look at Team Red. There's barely an Nvidia GPU in sight that's on sale, and even among those that are discounted, the prices aren't very good. On the other hand, AMD has cards marked down from already reduced prices, making Prime Day the perfect time to score a deal on a GPU.

By far, the best deal I've found is the XFX Speedster QICK319 RX 7800 XT. You can read more about the card in my RX 7800 XT review, but in short, it trades blows and sometimes even beats Nvidia's $600 RTX 4070 Super. The price right now is insane, too. This model normally sells for $520, but it's 18% off for Prime Day, bringing the price down to $427.
