- This is it; this is the big announcement that has been hyped up ever since CES with the Zen 2 architecture. This is AMD's latest seven-nanometer CPUs that is going head to head with Intel. This is a big one because they're changing from GlobalFoundries' 12-nanometer and they're going, as we said just before, to seven-nanometer. But they've also announced three new SKUs this time around, and we'll go over the details of them as well as looking at AMD's preview that they announced with the Navi GPU architecture. (electronic dance music) Getting straight into these details for you guys, the biggest improvement is the 15% IPC. That's instructions per cycle. This is a massive gain considering this is 2019, and we've seen in the past even with AMD going from Ryzen 1000 to 2000 on the CPUs, they only got around a 3% IPC increase. But this time around, it's absolutely massive. That is a 15% IPC over the previous 2000-series chips. They've also gone two times the cache size. This is very important of course to get those IPC improvements. AMD also stated this was a prerequisite to get the best gaming performance possible. Starting off with the first chip, and honestly, I think the most anticipated chip, at least when I announced these details at CES, this is the Ryzen 7 3700X. Eight cores, 16 threads. They're announcing a 4.4GHz single-core boost clock as well as 3.6GHz across all cores out of the box. This is coming in at $329, has 36MB of cache, as well as a 65-watt TDP. By the way, all the CPUs I'm talking about here today will be released on July 7th. The next CPU to go through is the Ryzen 7 3800X. Pretty much a similar thing to the Ryzen 7 3700X, except they have upped the clock speeds to 3.9GHz and a 4.5GHz single-core boost, as well as offering the CPU for $399. The TDP rating has also gone up from 65 watts to 105 watts, and we will talk about that a little bit later after we get over this next chip. This is the Ryzen 9 3900X. 3.8GHz boost across all cores and a 4.6GHz boost on the single-core performance. 70MB of cache in total. 105-watt TDP, as well as having 12 cores and 24 threads. They did show some benchmarks here. The first was the 3700X versus the 9700K. The next test that they showed was the 3800X versus the 9900K in PUBG. The FPS was looking really good for the Ryzen 7 3800X. This does indicate one thing to me personally, and that is that the eight-core, 16-threaded parts are going to only be on one die, and then that die is then connected to the input/output chiplet. AMD did talk about a chiplet design here. As I said at CES, I was looking forward to the eight-core, 16-threaded option because it looks like that latency is gonna be the lowest across all Zen CPUs. This in turn will make it AMD's gaming champion. But the last benchmark they showed was where the 3900X was going up against the 9920X, which is a HEDT platform CPU, and of course comes in at a much more expensive price point. This is $499. They showed it going 32 seconds versus 38 seconds in Blender, and these results were looking very good for AMD. The last thing AMD talked about in relation to the CPUs and also their Navi GPUs which we'll talk about later, too, was PCIe 4.0 support on the latest X570 motherboard chipsets. They're also still using DDR4 memory, but they didn't really give out any details in relation to the out of the box memory speeds supported, as well as how high things can go. But rumor has it from overclockers I've spoke to, they have got dual-channel sticks up to around 4.4GHz on the 16-core variant. Though of course, one thing you guys wanna know about of course is the all-core clock speeds. How much are these things realistically gonna overclock in the real world? I did manage to meet up with a few people behind the scenes here and get some sneak footage from the water cooling guys, and they were saying that there is a 16-core, 32-threaded option, and they did overclock it on water. Here's the kicker, though; it did go up to around 4.1GHz on what you would consider everyday overclocks. They did manage to get it just shy of 4.3GHz on all cores for those one-time runs. Stability-wise, it's looking like it's going to top out at maybe 4.1GHz, but keep in mind that is an engineering sample. But in the case of AMD, I hear that they do provide some of these chipset vendors the engineering samples that are really close to the retail samples. Another thing that I did also hear this time around was that this was one of the tightest releases ever in that they didn't let any information slip at all. In fact, a lot of the chipset vendors have all closed rooms where they had a person in charge. If third parties wanted to test coolers, for example, they had to send the cooler in to that lab, get that person in charge in that lab to test it, and then give them the results. Basically everything you guys heard with the rumors of going 5GHz across all cores was a little bit outlandish, but the IPC is super impressive. That 15% increase is absolutely massive, plus the fact that they've coupled it on seven-nanometer, and the power consumption, the 65-watt TDP, for example, on the 3700X, that is one thing to look forward to. Very impressive announcement, especially when it comes to the CPU side of things. Next up is Navi GPUs. These are going to be talked about more in-depth with a full detail reveal at E3. However, they did give us a hint of performance, and they did let us know some big news. That is it's the RDNA architecture, which is completely different from GCN. It's got PCIe 4.0 enabled. It's got faster clock speeds. It's also got better performance per clock, going at 1.25 times. And then they've also got 1.5 times better performance per watt. They are naming these the RX5000 series, and they did (mumbles) display the RX5700, and they did put it up against an RTX 2070. The game they decided to display was Strange Brigade. Obviously this is an AMD favorite title, but the performance was looking really good, especially since this does look like it's a mid-range card. But what does remain to be seen is a full SKU detail of how many models they're releasing. Is the Radeon 7 still going to be their top-performing GPU in the stack? Also on that note, the price, and also entry, mid-range, and high-end GPUs in this architecture all remain to be seen, but I will be reporting on that for you guys when I get the chance. With all that aside, I hope you guys enjoyed today's video. If you did, then be sure to hit that like button. Also, if you wanna see more of Computex, all the latest products that are coming out, and the inside scoop on them, then be sure to hit that sub button and ring the bell to get notified as soon as these videos drop. If you enjoyed this one as well, drop a comment. Let us know what you think about the new Ryzen 3000-series chips coming out on the CPUs. The Zen 2 architecture, that does look like it's very promising. I can't wait to get my hands on it, test it for you guys, run it through all the benchmarks, give you the ultimate verdict. With that aside, I'll catch you in another tech video very soon. Peace out for now. Bye. (electronic music)
