It has been some time, sorry it took so long - but today we have Episode number 65 with Leo focused on all things Zen 4 - ahead of the official launch. Let us know your views, so far, in the comments, we would love to hear. Have you already saved up for a new Zen 4 system? Or are you waiting to see how the reviews shape up first? 00:00 Start 00:31 Recap / leaks / Thoughts 02:16 Four models 02:55 Ryzen 9 7950X 03:29 What is coming / tech talk 07:45 Efficiency for desktop 08:15 CPU roadmap 08:32 New Socket AM5 09:49 EKWB Chart and heatspreader chat 10:42 Chipsets and capabilities 11:24 AMD EXPO Technology 12:01 V 12900k & Pricing 13:23 Ryzen 5 v Core i5 13:52 AMD Declaration 14:17 Leo chugs a beer and shares thoughts 15:42 AMD didnt make a big deal about / IGP 17:18 L2 cache has doubled 17:43 3D V-Cache versions 18:14 Leo is in a slightly different position … Leos' Notes AMD has been talking about AMD Zen 4 Raphael for months now https://bit.ly/3AMw41K Factor in the rumours and we have long known core counts, support for DDR5, the peculiar look of the new LGA CPU, and the fact the new AM5 socket is compatible with existing coolers. And now AMD has officially announced the details of Zen 4 Raphael desktop CPUs and X670 motherboards which will go on sale on 27th September https://bit.ly/3Rjes4z Ryzen 9 7950X $699 16C/32T 4.5GHz, up to 5.7GHz, 80MB, 170W Ryzen 9 7900X $549 12C/24T 4.7GHz, up to 5.6GHz, 76MB, 170W Ryzen 7 7700X $399 8C/16T 4.5GHz, up to 5.4GHz, 40MB, 105W Ryzen 5 7600X $299 6C/12T 4.7GHz, up to 5.3GHz, 38MB, 105W Any comparisons between Ryzen 9 7950X and Ryzen 9 5950X use different chipsets and different RAM Any comparisons between Zen 4 and Alder Lake ignore the imminent 13th Gen Raptor Lake Process for chiplets down from TSMC 7nm to TSMC 5nm. IO die uses TSMC 6nm rather than Glo Flo 12nm so it's TSMC across the board. Presumably the X670 and B650 chipsets are also made by TSMC. DDR5 memory support only. Aim for DDR5-6000 and budget £250-£300 for a 32GB kit AM5 uses a new LGA 1718 socket that can supply up to 230W Ryzen 9 TDP is 170W Supports PCIe Gen 5.0 graphics and storage X670 Extreme, X670, B650 Extreme and B650 chipsets segmenting PCIe Gen 5 graphics and Gen 5 storage AMD Advantage - both CPU and GPU along with Direct Access Memory Ryzen 7000 includes a tiny RDNA 2 IGP L2 cache has doubled from Zen 3, L1 and L3 remain the same. Cache latency is slightly slower for Zen 4 than Zen 3 Workloads that fit in the new, larger L2 should be very fast 3D V-cache versions are due to be announced at CES in January 2023 #Zen4 #AMD #Ryzen ... https://www.youtube.com/watch?v=3C3PQYFtm4w

We can all agree that the last 12 months have been challenging and stressful for everyone, and I wanted to utilise Kitguru in a positive way for a great cause. Over the next two weeks, we are holding a silent auction via email for our readers and supporters, with 100% of the proceeds being donated to the Northern Ireland Children’s Hospice. Additionally KitGuru will be donating the same amount as the winning bid, effectively doubling the donation to the charity. This is a very worthy cause that we want to support this year and everyone who enters will know that they are potentially going to help children in real need. The NI Childrens Hospice has been helping children with life-limiting and life-threatening conditions as well as their families for over 35 years. It is a cause that we are very much in support of and we hope many of our readers will be interested in getting involved on some level. We discussed possibly holding this auction on the UK’s biggest platform – EBAY, however we really wanted to involve as many of our readers as possible, without directing it towards the mass public who are not associated with the KitGuru audience. I didn’t want this system going to a random person in the UK who doesn’t really understand what we are trying to do. KitGuru will be matching the winning bid for the chance to own this Gaming PC, doubling the overall amount we donate. KitGuru will also give the winner a full 1 year warranty directly. So if any component or peripheral was to fail in the first year, we will replace it and it will be shipped to your door, completely free of charge. In the gallery below, you can see the gaming PC and accompanying peripherals that make this build, including a 144hz gaming Monitor. Here are the full specifications for the system: AMD Ryzen 3800X CPU Asus ROG Strix B550-F (Wi-Fi) Gigabyte Gaming OC 5700 XT T-Force Xcalibur 16GB kit (2X8GB) DDR4-3600 Cougar Trofeo Case Cougar Aqua 240 AIO Cooler Cougar GEX 650W PSU Cougar Attack X3 Keyboard RGB Cougar Bunker mouse Bungee RGB Cougar Revenger S mouse RGB Cougar Neon mouse mat RGB Viper VPN100 1TB M.2 SSD AOC 24G2U 24” 144Hz monitor While the prices of these components are constantly changing, the current market value as we go live to print today is around £1700. Special thanks to all the great companies involved that jumped at the chance without questions to help such a great cause. Entering is really simple. If you want to be in with a chance to get this system delivered to your door just send your single best ‘bid’ to ‘hospiceauction@kitguru.net‘. Subject field ‘Bid for Hospice Charity System’. Please do not send your address or any personal information in the email – we just need to know your final bid for the system in pounds sterling �� ... https://www.youtube.com/watch?v=OsMV2k-rFFE
