AMD Ryzen 7000 Desktop Processors Launched: Zen4, Leadership Performance
AMD is expected to announce the Ryzen 7000 desktop processor series based on the "Zen 4" architecture, and we're reporting from Austin Texas.
23:02 UTC: AMD to introduce "Zen 4", RDNA3, Zen 4C and XDNA architecture over the next few quarters.
23:04 UTC: "Zen 4" designed to be the fastest core for gamers and most compute for creators.
23:05 UTC: Zen 4 IPC uplift is 13%, up to 5.70 GHz clocks, up to 29% single-thread performance boost.
23:06 UTC: Ryzen 9 7950X provides up to 35% gaming performance boost, up to 48% creator performance boost. Crushes i9-12900K.
23:08 UTC: 47% performance/Watt leadership over the i9-12900K
23:08 UTC: Four SKUs at launch, same core-counts as previous-generation:
23:09 UTC: All four SKUs beat the i9-12900K at geekbench 1t, including the 7600X.
23:10 UTC: 7600X beats 12900K gaming performance by 5%
23:11 UTC: "Zen 4" built on 5 nm.
23:12 UTC: 13% IPC uplift, new core front-end design, AVX-512 support, all on 5 nm:
23:13 UTC: 13% IPC uplift is a geomean over dozens of benchmarks:
23:14 UTC: Bulk of the IPC contribution comes from the new front-end:
23:15 UTC: AVX-512 support added for AI acceleration:
23:16 UTC: VNNI and AVX-512 instructions add 2.5X nT INT8 performance.
23:17 UTC: TSMC paid a big role in co-development of the chiplet at the process-level.
23:18 UTC: The Zen 4 CCD is 18% smaller than the Zen 3 CCD.
23:19 UTC: Incredible isopower and isoperformance gains:
23:19 UTC: Efficiency even at 170 W TDP levels.
23:20 UTC: The Zen4 core is 47% smaller than the "Golden Cove" P-core of "Alder Lake:
23:21 UTC: Roadmap shows Zen4 3DV cache on 5 nm, and Zen 5 on 3 nm and 4 nm:
23:22 UTC: There will be no let up in AMD innovation: Mark Papermaster
23:23 UTC: AM5 platform will be relevant going into 2025+
23:24 UTC: AMD delivered on its AM4 promise.
23:25 UTC: 1718-pin LGA, up to 230 W power delivery, DDR5 and PCIe Gen 5, cooler compatibility with AM4.
23:26 UTC: Four chipset: X670E, X670, B650E, B650. X-series in September, B-series in October:
23:27 UTC: Gen 5 NVMe SSDs by November:
23:28 UTC: DDR5 is the only memory choice for AM5, but with the new EXPO technology.
23:29 UTC: EXPO a royalty-free technology for memory makers:
23:30 UTC: AM5 motherboards start at $125.
23:30 UTC: AM5 supported over several generations, just like AM4
23:31 UTC: Available September 27:
23:32 UTC: AMD Teases RDNA3, more than 50% performance/Watt gain over RX 6000 series. Launch within 2022.
23:33 UTC: AMD demoes RDNA3 on Zen 4
23:34 UTC: Wrapping up:
23:17 UTC: TSMC paid a big role in co-development of the chiplet at the process-level.
23:19 UTC: Incredible isopower and isoperformance gains:
23:23 UTC: AM5 platform will be relevant going into 2025+
23:24 UTC: AMD delivered on its AM4 promise.

360mm coolers are necessary
My 5900x was hitting temps of high 80s and flirting with 90 when I was doing intensive work loads while using the NH-U9S. With the H100i AIO the CPU gets to maybe mid 70s when doing intensive work loads.
The point is to get you to go higher than you would like or need and spend more money in the process.
In marketing it is called a decoy product.

2 RDNA2 CUs on 6nm is ≤4mm² so nothing extravagant. Also it will be an extra added value (performance wise) in relation with the competition so even in the commercial sector (Optiplex,ProDesk, ThinkCentre etc) that AMD wants to get more share, although at first glance not important at all, it enables in each country local HP/Dell/Lenovo account managers to convince more easily local ITs to migrate from Intel to AMD offering an additional bullet point for local office Lan parties.
Lol, just kidding, like i told you i just find it interesting that AMD doesn't want to diversify at all performance wise, essentially justifying for that sector of the market the low performance IGP strategy that Intel was using all these years!

AMD said that the sweet-spot is 6000 MT/s, that's very impressive if you consider that the official support regarding (non-OC) memory clock is 3600 MT/s for dual channel!

2x1R 3600 MT/s
2x2R 3600 MT/s
The AMD Ryzen 9 7950X was tested on ASUS ROG Crosshair X670E Extreme motherboard equipped with 32GB of DDR5-6000 memory. The CPU reached maximum boost frequency of 5759 MHz (as per detailed Geekbench data), so a bit higher than advertised boost clock of 5.7 GHz.
In Geekbench V5, Intel Raptor Lake i9-13900K with 24 cores and 32 threads is 4.4% faster in single-core and 8.4% faster in multi-core tests than Ryzen 9 7950X. On the other hand, AMD’s new flagship CPU is 31%/47.8% faster than 5950X and 14.5%/41.2% faster than i9-12900K respectively.

Leadership Performance, Yep.
