WEBVTT 00:00:00.000 --> 00:00:04.080 The launch of AMD Zen 4 processors is imminent! 00:00:04.080 --> 00:00:11.980 So what should you know before running out to buy one? The first thing you'll probably notice if you buy a Zen 4 or Ryzen 7000 series chip is 00:00:11.980 --> 00:00:16.480 that AMD has finally switched to a more Intel-like LGA socket. 00:00:16.480 --> 00:00:22.280 This is actually Team Red's first ever mainstream consumer LGA socket, which AMD is using to 00:00:22.280 --> 00:00:31.640 increase pin density. AM5, as they're calling it, increases the pin count from 1331 to 1718, which will allow 00:00:31.640 --> 00:00:38.680 the CPU to receive up to 230 watts of power, increase bandwidth for DDR5 and PCIe 5.0, 00:00:38.680 --> 00:00:45.240 and make the CPU itself more durable. But of course, you'll have to take care not to bend the pins on the motherboard. 00:00:45.240 --> 00:00:49.880 Oh wait, back up a second. DDR5 and PCIe 5? 00:00:49.880 --> 00:00:54.280 That is indeed what I said. The Zen 4 features support for both. 00:00:54.280 --> 00:00:58.320 But you'll need to pay attention to what motherboard you're buying if you want PCIe 00:00:58.320 --> 00:01:03.000 5.0. It's potentially important for future graphics cards, but the only chipset that features 00:01:03.000 --> 00:01:06.360 it as standard is the new X670 Xtreme. 00:01:06.360 --> 00:01:11.440 However, DDR5 will be supported by Zen 4, regardless of what chipset you have, along 00:01:11.440 --> 00:01:14.560 with a new feature called Expo. 00:01:14.560 --> 00:01:18.480 But Expo isn't a fancy soiree at the London Crystal Palace. 00:01:18.480 --> 00:01:23.440 Instead, it's AMD's answer to Intel's XMP memory profiles. 00:01:23.440 --> 00:01:27.520 And yes, I realize that's like saying ATM machine, but we're trying to make things 00:01:27.520 --> 00:01:32.440 easy here. Okay. Anyway, this might sound a little confusing if you're used to setting your memory speeds 00:01:32.440 --> 00:01:35.800 and timings with DOCP or EOCP. 00:01:35.800 --> 00:01:41.360 But the thing is, these solutions are only offered by ASUS and Gigabyte, respectively. 00:01:41.360 --> 00:01:46.760 Expo, by contrast, was developed by AMD itself, so you should be able to get one-click memory 00:01:46.760 --> 00:01:49.760 overclocking, regardless of who made your motherboard. 00:01:49.760 --> 00:01:57.360 Now, here's the nitty-gritty. AMD's internal benchmarks, taken with a grain of salt, indicate 13% more instructions 00:01:57.360 --> 00:02:02.800 per clock cycle, partly thanks to a larger cache size as well as better branch prediction. 00:02:02.800 --> 00:02:07.280 But the bigger advancement is probably the 5nm process that Zen 4 is built on. 00:02:07.280 --> 00:02:12.080 AMD partnered with TSMC to develop a chip that would get higher performance despite 00:02:12.080 --> 00:02:15.320 an overall smaller die size than Zen 3. 00:02:15.440 --> 00:02:19.200 Team Red also included support for AVX 512 extensions. 00:02:19.200 --> 00:02:23.560 And if you have no clue what that is, it's a set of instructions that Intel actually 00:02:23.560 --> 00:02:27.280 axed from its Alder Lake CPUs in favor of power efficiency. 00:02:27.280 --> 00:02:32.800 AMD clearly thought it was still worth keeping in, so they baked in partial AVX 512 support 00:02:32.800 --> 00:02:35.960 in order to help with deep learning and AI applications. 00:02:35.960 --> 00:02:41.360 And speaking of power efficiency, we're looking at 62% less power draw for the same performance 00:02:41.440 --> 00:02:47.120 as Zen 3, which AMD attributes to not only the new manufacturing process, but also lessons 00:02:47.120 --> 00:02:52.240 they learned in the mobile arena. Of course, it remains to be seen how all these improvements will translate to performance 00:02:52.240 --> 00:02:58.800 in the applications you use the most. And AMD has already admitted you shouldn't expect Earth's shattering performance from 00:02:58.800 --> 00:03:03.440 the integrated RDNA2 graphics compared to their upcoming APU lineup. 00:03:03.440 --> 00:03:07.440 But at least it looks like integrated graphics are coming standard in case you just need 00:03:07.440 --> 00:03:12.520 a display out. It won't be long, though, until we get independent testing available for broad consumption, as 00:03:12.520 --> 00:03:17.040 the Ryzen 7000 series is due out on store shelves on September 27th. 00:03:17.040 --> 00:03:21.760 And more variations, including cheaper, non-X versions, should be coming our way sometime 00:03:21.760 --> 00:03:27.720 next year. Best of all, there's no price increase compared to what Zen 3 sold for, and there's actually 00:03:27.720 --> 00:03:30.720 a discount at the top end of the product stack. 00:03:30.720 --> 00:03:34.640 Let's all just keep our fingers crossed that we can actually get chips at MSRP instead 00:03:34.640 --> 00:03:39.640 of selling our spleens to some dude in a back alley. I don't want to do that again. 00:03:39.640 --> 00:03:45.640 And I don't want to keep doing this video because it's over. Thanks for watching!
