Final Thoughts / Conclusions

Summary: A powerhouse of a CPU: 10/10!

Ever since Ryzen (Zen1) AMD has been hitting winners – with Zen2 (series 2000) and Zen3 (series 5000) bringing big performance improvements – while still using the same AM4 platform. While some features (e.g. PCIe4, USB 3.2, etc.) may not be supported, you could still have gone from a 1st gen Ryzen to series 5000 16C/32T monster on the same platform; thus you’d be going to the very top of desktop performance beating anything the competition (Intel) had released on their latest platform.

AMD had to finally refresh the platform in order to bring new technologies support – DDR5 primarily, but also PCIe5, USB 4.0 – and they could have easily just stuck with that. But no, AMD has instead brought a revolutionary Zen4 CPU – bringing AVX512 512-bit SIMD computing (and extensions) just when Intel has killed them off due to their hybrid design.

However, both due to increased clocks and core improvements, even legacy code flies – all code is between 40% to 100% (2x) faster than Zen3 and thus also beats Intel’s very top ADL processor into dust. With AVX512 extensions (IFMA, VNNI), the improvement is even larger, 2.5x. There is nothing this CPU cannot handle – but then again this is the top-end 16C/32T version.

Price wise, if we’re talking the top end (7950X) this is 13% launch price cheaper – ending up 2x better value than the previous top-of-the-range (5950X) which is great value for money. Intel will have to reduce prices quite drastically to compete.

The only negative is the greatly increased TDP (170W vs. 105W on Zen3) – although the turbo power (~240W) is similar to Intel’s ADL and likely (from rumours) still less than Intel’s future RPL. There is also an option to disable turbo as the base speed is so high and the CPU is so fast although not everybody will be happy with that.

Naturally, a new AM5 mainboard is required – but hopefully it will last you many more updates than the competition – possibly Zen7 (!) with 64C/128T if things progress in the same manner we’ve seen until now. DDR5 memory has come down somewhat by now and brings much needed memory bandwidth improvements and USB 4.0 is very much needed for (very) high speed external devices. Not to mention PCIe5 support for future NVMe and GP-GPU components.

Also keep an eye for the 3D-VCache version with much larger L3 cache if your workloads are large and you are going for the single CCX (8C/16T) versions.

“Good things come to those who wait” it is said; in this case AMD has definitely delivered! Intel will need a miracle to beat this.

  • 42% faster than Ryzen 9 5950X (Zen 3) in Legacy Integer
  • 30% faster than Ryzen 9 5950X (Zen 3) in Legacy Floating-Point
  • 100% faster than Ryzen 9 5950X (Zen 3) in AVX-512
  • 30% faster than Ryzen 9 5950X (Zen 3) in Streaming (crypto/hashing) tests
  • 48% faster than Ryzen 9 5950X (Zen 3) in non-SIMD floating point
  • 94% faster than Ryzen 9 5950X (Zen 3) in SIMD floating point

AMD Ryzen 9 7950X breaks four HWBOT world records with AIO cooler

The flagship 16-core AMD Raphael CPU needs no exotic coolers to break world records. In total, four records now been broken by Sampson and blueleader who got a green light to share their Ryzen 9 7950X results. The fact that all four have been broken with the latest CPU are not impressive, but the fact that none used liquid nitrogen certainly is.

Using either AORUS X670E Xtreme, ASUS ROG Crosshair X670E Extreme, ASRock’s X670E Taichi or MSI X670E MEG ACE motherboards and Corsair H115i liquid cooler AIO cooler, both overclockers managed to break four records: Cinebench R15, R20, R23 and 7-zip.

The CPUs have been running at 5.4 to 5.5 GHz with all cores with temperatures between 87°C to 108 °C if Benchmate data is to be considered. The data also shows that Ryzen 9 7950X has been running with 226W to 244W max power, so within the maximum allowed range for AM5 socket.

Hvorfor blir ikke zen 4 lansert med bare V-cache modeller for topp SKU's? Eneste ulempen med V-cache er vel høyere varmeutvikling og høyere produksjonskostnad. Men for entusiastmodellene er vel dette en liten pris å betale for mye bedre ytelse.

Eneste grunnen jeg kan se ellers er for å lansere dette senere, f.eks q2 2023 for å hele tiden kunne gi markedet "noe nytt", mens neste generasjon utvikles.

For min del, så er GPU mer aktuellt dette året, enn å forbedre noe HK + CPU, da jeg er på 5900x og det er jo mer enn nok muskler til alskens egentlig. Så en oppgradering må nesten bli en sekundær PC og mer i entusiastsporet om jeg skal hive meg på. For min del er det sikkert mer fornuftig å stå over en generasjon? Men, fornuften seirer jo ikke alltid. Uansett så skal det bli greit med ny grafikk for å få til ordentlig 120 Hz 4K gaming, antar jeg da. Har ikke gamet på PC på mange månder nå etter at Xbox X kom i hus.

Det kan jo hende at det er flere som er nokså lik meg som har ordnet seg HW fra forrige generasjon og konsoll. Altså vil AMD, Intel og Nvidia måtte ta litt hensyn til markedene. Jeg tipper at folk har nok krefter i sine rigger, men at lysten kan ta overhånd for noen?

Edit: Oh, helvete så mye sider som var kommet til siden jeg valgte å svare på dette innlegget som er nokså gammelt ;)

Litt tillegg informasjon til 48k Cinebench runnet:

tldr:

  • CPU temp sensor goes all the way down to -49
  • They could run "full pot" with their dual CCD 16core 2GMI sample -> in their words its more behaved than Zen3
  • IGPU acts like Raven ridge and Picasso APU's when cold
  • With LN2 mode enabled in bios you wont be voltage limited in ryzen master (limit is set by motherboard VRM)
  • Like previous stated, auto:1:1 is recommended settings for 24/7 (MCLK+UCLK should run synced the fastest you can)
  • With Zen3 you had to lower infinity fabric speed from ~1900mhz to ~1400mhz when running LN2. In this video they had lowered memory clock from ~3200mhz to ~1800mhz with their Zen4 sample 
  • Seems like default power limits for the 7950x is 180 TDC and 250 EDC
  • "VDDG CCD" and "VDDG IOD" are mashed together into "VDDG MISC".
  • Need to play with 4 main voltages when you overclock: VCORE, VSOC and VDDG MISC together with VDIMM
  • They have one setup on normal ambient cooling running 2200:3200:3200 (this should be the aim for normal 24/7 settings) (6400MT/s memory speed)
  • Its still easier to overclock the 7600x and 7800x compared to 7900x and 7950x with LN2 because single CCD cpus only have one GMI links compared to the dual CCD cpus which have two (GMI is still a limiting factor with Zen4 under LN2)
  • The 7950x have the best silicon for cpu clockspeed (binning)

Er VDDP og VDD18 også borte? Helt greit om de er det for meg ;)

https://videocardz.com/newz/amd-ryzen-7950x-7900x-7700x-7600x-stock-cinebench-scores-leaked

In this short article we will share Cinebench R15, R20 and R23 scores for all AMD Ryzen 7000 CPUs in comparison to their 5000 predecessors. All Ryzen 7000 CPUs were tested with stock settings with AMD provided review kit, featuring premium X670E motherboard and G.Skill DDR5-6000 memory (2x16GB). AMD Ryzen 5000 CPUs with DDR4-3200 memory.

*edit*

If other leaks are to be believed, a stock 13900k scores 2290 ST and 35700 MT in Cinebench r23
