 Oh heck yeah, I've got some brand new GPUs in the oven. Let's see what Mr. Jensen has in store for us. Wait, it's just... Yup, yeah, Nvidia finally announced the RTX 4090, 4080, and also the RTX 4080 but slower. To be clear, the RTX 4090 looks freaking incredible and gamers have a lot to be excited about here, but Nvidia has also left out a lot of key details that have me very concerned about just how much of a performance increase you're gonna get if you're not willing to sell a kidney. I'm always willing to sell stuff though, and that's why we're talking about today's sponsor. Zoho CRM!

Out of the gate, the RTX 4090 looks like a monster and not in the way we thought it would either. Although the details and Jensen's announcement were light, he did mention a doubling of rasterization performance and a quadrupling of ray tracing performance and the specs back him up, but the RTX 4090 having 16,300 and 8,680 frames per second, and it's not even a super good GPU. The RTX 4090 has a 16,384 CUDA cores and a boost clock of 2.52 GHz. Even without architectural improvements, this thing buries the 3090. Going into the event, there are rumors that the 4090 would draw up to 600 watts of power, but impressively Nvidia has been able to have this huge bump in CUDA cores and clock speeds while maintaining the same 450 watt TDP of the RTX 3090. Which to be clear, still a lot of power, but it's not an asinine amount of power. Given how much of a performance uplift the RTX 4090 offers, I'm impressed they were able to keep the price to $1,600. And yeah, that's a stupid amount of money for a GPU, but the $100 increase over the RTX 3090 is less than half inflation in the same amount of time. And before this announcement, I was very concerned it would cost closer to two grand. That said, currently you can get a 3090 Ti for a bit over $1,000, so the actual value proposition on the RTX 4090 is a bit more difficult. With a release date of October 12th, hopefully we'll be able to properly test one out soon and figure out if it's really worth it. Now we get into the more questionable side of the announcement, the 4080s. There are two different RTX 4080s, a 12 gigabyte model and a 16 gigabyte model. What is strange though is that these are completely different cards with completely different specs. Now Nvidia did not give us any non ray traced performance data, nor did they share with us the crucial memory bandwidth spec, but what we do know isn't promising. With 7,680 CUDA cores, the 12 gigabyte RTX 4080 has a thousand less CUDA cores than the RTX 3080. Ow. While the 16 gigabyte model falls behind the RTX 3080 Ti's core counts. The saving grace here is the clock speeds at 2.6 and 2.5 gigahertz respectively. On paper, these GPUs are still ferocious and that isn't even taking into account the raw architectural advantages that they get thanks to TSMC's 4N node compared to Samsung's 8 nanometer. You just get the faster 16 gigabyte 4080 that comes with the 16 gigabyte 4080, but you just get the faster 16 gigabyte 4080 then, right? Not so fast. In Nvidia's own performance data, it shows the 12 gigabyte and 16 gigabyte versions are nearly tied in flight sim. While in Warhammer and Cyberpunk, the 16 gigabytes pulls an amount ahead. Given the $300 price difference, there's a good chance the 12 gigabyte model will be just the better buy over the 16 gigabyte because you're already in it for $1,200. You might as well just save up a little bit more for the much stronger RTX 4090. I am deeply suspicious that the 12 gigabyte 4080 was supposed to be the RTX 4070, but then the GPU market crashed, Ethereum went proof of stake, and they're sitting on months worth of stock of the RTX 3000 series. So they cannot justify a $900 4070. Easy fix though. Just call it a 4080 instead. All of this though is me speculating about the rasterization performance of these GPUs, AKA how it performs in non-ray traced games. If you care a lot about ray tracing though, RTX 4000 series looks damn good. Nvidia claims a two to four times increase in performance with ray tracing on, and they achieve this through a couple different methods. First, throw more hardware at it. Like so much that people might start actually turning ray tracing on. Next, you make it run better with shader execution reordering. Nvidia didn't get into as much detail about this as I was hoping, so I'm just gonna make an educated guess, and if I'm wrong, correct me down below. Ray tracing is naturally a single threaded task, because you can't calculate like the third bounce of light until you've already calculated the first two. This can lead to the shader engine, which figures out how light and dark various pixels should be. It just kinda wait around while the ray tracing is being calculated. But using the magic of shader execution reordering, apparently Nvidia can make the process more parallel leading to it. Two times more efficient ray tracing, and FPS boost of about 25%. The third way Nvidia improved ray tracing performance is by giving us DLSS 3. In the past, DLSS would use AI to turn a lower resolution source into a higher resolution output, but with DLSS 3, Nvidia is able to create a new fully AI generated frame without the intervention of the CPU by just using the motion information that was already there in DLSS 2. I'm not totally sure how I feel about this. In cinematic games like Cyberpunk or Flight Sim, I'm sure it works great, but I'm not totally sure I want to turn it on in a competitive shooter, since it kinda sounds like motion smoothing through the magic of AI instead of actually adding more FPS. But I know what a lot of you are thinking right now. Ray tracing doesn't matter because the games you love don't support it and the performance hit is just way too much. And honestly, I agree with you. The best ray tracing experience I've had is in Minecraft, and I didn't even use the RT cores for that, which is why I'm super stoked for another thing Jensen announced today, RTX Remix. In the past, adding ray tracing to a game that was developed on say, DirectX 8 or DirectX 9 was basically impossible for modders unless they had access to the tools used to develop the game and a metric buttload of time. Now, using RTX Remix, modders won't need access to specialized tools and will only need to spend an imperial butt cheek of time to remaster your favorite old games. RTX Remix works by capturing the textures, geometry, lighting, and cameras by intercepting the draw calls, interpreting them as distinct assets, and then reassembling them all back into a scene. Nvidia went ahead and remastered Portal into Portal RTX using this tech and will be available as free DLC in November. Honestly, this is probably my favorite thing announced today. Also, if someone could give Valheim the RTX Remix treatment, you'll be my hero. What creators will be excited about though is AV1 support and Nvidia didn't even mention it in the presentation, but it's there. RIP, Ark, you never even lived. One thing I want to circle back on though, the pricing. I've seen a lot of people in the comments respond to the pricing accusing Nvidia of being super greedy, and honestly, I don't think that's the case. We know that TSMC's prices have risen by at least 20, maybe even 30%, and Nvidia's 4080 and 4090 dyes are massive. I think they plan on releasing these at potentially even higher prices, but had to rethink it after the whole GPU crash. Do you really think if this was a super profitable release, EVGA would have jumped ship? What these prices definitely do though is leave the door wide open for AMD's RDNA3, because Nvidia probably just can't make them any lower. I highly doubt Team Red will be able to take on the 4090, but the rumors suggest AMD could be very competitive against the 4080s in performance and destroy Nvidia in efficiency. We'll have to wait until November 3rd to find out though, but what you can do now is find out who sponsored this video.
