1 00:00:00,000 --> 00:00:04,080 The launch of AMD Zen 4 processors is imminent! 2 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 3 00:00:11,980 --> 00:00:16,480 that AMD has finally switched to a more Intel-like LGA socket. 4 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 5 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 6 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, 7 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. 8 00:00:45,240 --> 00:00:49,880 Oh wait, back up a second. DDR5 and PCIe 5? 9 00:00:49,880 --> 00:00:54,280 That is indeed what I said. The Zen 4 features support for both. 10 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 11 00:00:58,320 --> 00:01:03,000 5.0. It's potentially important for future graphics cards, but the only chipset that features 12 00:01:03,000 --> 00:01:06,360 it as standard is the new X670 Xtreme. 13 00:01:06,360 --> 00:01:11,440 However, DDR5 will be supported by Zen 4, regardless of what chipset you have, along 14 00:01:11,440 --> 00:01:14,560 with a new feature called Expo. 15 00:01:14,560 --> 00:01:18,480 But Expo isn't a fancy soiree at the London Crystal Palace. 16 00:01:18,480 --> 00:01:23,440 Instead, it's AMD's answer to Intel's XMP memory profiles. 17 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 18 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 19 00:01:32,440 --> 00:01:35,800 and timings with DOCP or EOCP. 20 00:01:35,800 --> 00:01:41,360 But the thing is, these solutions are only offered by ASUS and Gigabyte, respectively. 21 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 22 00:01:46,760 --> 00:01:49,760 overclocking, regardless of who made your motherboard. 23 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 24 00:01:57,360 --> 00:02:02,800 per clock cycle, partly thanks to a larger cache size as well as better branch prediction. 25 00:02:02,800 --> 00:02:07,280 But the bigger advancement is probably the 5nm process that Zen 4 is built on. 26 00:02:07,280 --> 00:02:12,080 AMD partnered with TSMC to develop a chip that would get higher performance despite 27 00:02:12,080 --> 00:02:15,320 an overall smaller die size than Zen 3. 28 00:02:15,440 --> 00:02:19,200 Team Red also included support for AVX 512 extensions. 29 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 30 00:02:23,560 --> 00:02:27,280 axed from its Alder Lake CPUs in favor of power efficiency. 31 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 32 00:02:32,800 --> 00:02:35,960 in order to help with deep learning and AI applications. 33 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 34 00:02:41,440 --> 00:02:47,120 as Zen 3, which AMD attributes to not only the new manufacturing process, but also lessons 35 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 36 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 37 00:02:58,800 --> 00:03:03,440 the integrated RDNA2 graphics compared to their upcoming APU lineup. 38 00:03:03,440 --> 00:03:07,440 But at least it looks like integrated graphics are coming standard in case you just need 39 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 40 00:03:12,520 --> 00:03:17,040 the Ryzen 7000 series is due out on store shelves on September 27th. 41 00:03:17,040 --> 00:03:21,760 And more variations, including cheaper, non-X versions, should be coming our way sometime 42 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 43 00:03:27,720 --> 00:03:30,720 a discount at the top end of the product stack. 44 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 45 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. 46 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!
