Ryzen a little late to get 2 rumours

Better late than never to get previews of the second coming of Ryzen up, from two additional sources above and beyond the post below.  Pinnacle Ridge is poised to release next Thursday but there are a few details which have surfaced for our enjoyment about the chips themselves as well as the new Wraith coolers.  The Tech Report offers the few tidbits they are currently able to disclose, such as the infection of RGBs in the Wraith Prism cooler, while TechARP have posted a few leaked benchmarks which may or may not reflect reality as well as a look at the reviewers kit.  We know the Ryzen 5 2600X has six cores and the Ryzen 7 2700X sports eight but so far the only other thing we know for sure is what they both look like physically

OK what do you think it will be for some sorts of Silicon Lottery sorts of Ryzen 2000 series SKUs that are lucky enough to come off the diffusion lines at the chip fabrication plant with some better Thermal/Performance metrics.

A Ryzen 7 2700X golden sample that may just beat that 4.3 and XFR whatever or even average Manual overclock and not require a voltage high enough to send any transistor atoms flying out and degrading the SKU to the point of early failure.

I wish someone would take a look at GF's 14nm first generation Razen at some later Ryzen SKU fab samples that have over time shown some average improvment just to give a refrence to be able to guesstimate what that Second generation Ryzen/Zen+ SKUs could possibily see as that GF 12nm process improves over time.

What do you expect for some of these first Ryzen 2/Zen manual overclocks on air or on water looking back at first generation Ryzen. The firmware has to be better this time around also for Zen and AM4/400 series chip sets and even for any 400 series MB's with their traces routing tweaked for better performance less error correction needed and higher memory clocks.

I'm also wanting to see AM4 400 series MBs improvements with respect to any new traces(PCIe/USB/others) routing to correct any deffiencies(siginal interfence/other) that may degrade optimal MB performance in addition to any reworking of slot/socket placements and other such MB tweaks to firmware and features/feature sets.

Looks interesting for Zen+ and wikichip's updated entry om that Zen+ design, including the 400 series MB/Chipset features.

"Memory Subsystem[edit]

When AMD presented their paper at ISSCC 2018, WikiChip was able to confirm with AMD's SoC architect that Zen's L2 latency was always designed to be 12 cycles. In fact all Zen-based microprocessors (including EPYC, Ryzen Threadripper, and Zen-based APUs) have an L2 latency of 12 cycles for all patterns. Only mainstream Zen-based Ryzen processors (i.e., Summit Ridge) have a latency of 17 cycles. The problem has been sorted out with Zen+." (1)

A new feature AMD has added to the 400-series chipset is "StoreMI", a technology with very similar capabilities to Intel's Smart Response Technology which attempts to combine the benefits of fast, but expensive, SSDs along with cheap high-capacity, but slow, HDDs. StoreMI combines the two storage devices into a single virtual drive (since letter drive on Windows and automatically manages and moves the data across the drives. Essentially, the chipset uses the SSD as a cache for traditional hard drives. The idea is to keep the most recent and most accessed data on the SSD in order to improve real-world responsiveness while keeping the less used data in the slower mechanical hard disk in order to preserve the capacity of the SSD. It’s worth noting that this hierarchy of secondary storage devices can actually extend to main memory. Up to 2 GiB of RAM may be configured and reserved as another level of cache for the HDD on top of the SSD. (1)

The whole Wikichip entry has the latest Zen+ Preliminary information and gets updated quickly when new info becomes available.

Note the strangely missing 2800/2800X.

Not strange at all. The 1800X shouldn’t have existed. It was too expensive (nearly double the price of the 1700, and for what tangible difference?) It added another bin for the 8-core to differentiate bringing the total number of near identically performing Ryzen 8-cores up to four. This is especially bad when you remember that none of these are being overclocked higher than 4GHz, or lower than 3.8 so there is no easy criteria to sell this binning on. Then there’s the fact that it forced the entry price into Threadripper too high. The 8-core Threadripper was not competitive with Intel’s Skylake-X entry CPUs because of its price.

It has always been the case with the top of the line that you pay a large price premium for a rather small increase in performance. Perhaps people just accepted that with intel parts, but they take note of it when it is an AMD part. Still, they seem to be leaving some room at the top for something.

Well TR is what AMD probably wants users to look to for any performance segement above the Ryzen 7 2700X and at least AMD is not segementing it products by PCIe lanes as agressively as Intel segements its offerings.

HEDT is probably where AMD expects any users to go if they want more performance for Gameing above the 2700X and that's scheduled for TR-2nd-Gen in the 2H of 2018.

Maybe any 2800/2800X SKUs would have very little to no overclocking headroom and Folks would do the same with the 2700/2700X that they did with the 1700/1700x and buy that instead of the 1800X. So a 2800X with little overclocking headroom would not sell as much. It's because it was more cost effective to get the 1700/X and manually overclock those and get the same relative performance as the 1800X at the time at a very good savings.

That's the orginial intent of overclocking anyways for someone to purchase the lower binned SKUs and get them to clock/perform like the higher binned SKUs and save money doing so.

Intel was the one that succeded in monetizing by segementing for any overclocking with their K series parts, the only Intel parts offerings with unlocked clocks. AMD has no "K" classification AMD mostly does not lock the clocks on the majority of its SKUs. So maybe AMD wants there to be some Overclocking headroom in its top end Rayen 7 SKUs so overclocks can be higher. Intel sure intentionally made sure its top end K series parts have some artifically engineered/binned headroom to give its K sreies customers something to expect for their extra cost($$$) required on these K series Intel parts.

The Ryzen 2000 series parts are sure priced lower at their at introduction than the first generation Ryzen parts and AMD has improved some latency and memory clock metrics on the Ryzen 2000 series and AM4/400 series MB/chipsets. That's still going to be better than the first generation Ryzen parts and the MB makers have more experience with the AM4/300 series MBs to get more tweaks into the AM4/400 series parts with the 400 sreies chipsets getting all the Tweaks and new features that the 300 serices chipsets lack.

The New AM4/400 series MB's are getting more attantion from their respective makers for all sorts of transparent tweaks to all those AM4/MB's many controllers and their firmware as well as any MB trace layouts that are redone to improve performance and reduce any MB/Bus error rates that have to be corrected for via controller/firmware error correction circuitry and that improves system performance also. Power delivery subsystems are getting better also and that's always great for power used and heat generated on the latest AM4/400 series MB offerings.

Thanks, @Jeremy, for this info.

What do you mean by "...infection of RGBs in the Wraith Prism cooler..." though?

Surely there's no virus for LEDs?

RGB/LED is itself an Infection and that's nothing to do with any computer virus. Think about your average Monobrow that's so enamored with all those flashy lights and that's the infection right there. Does LED/RGB add anything to the Wraith Prism cooler's actual cooling ability or is it more to do with the vanity of the unwashed gaming masses!

It's too much like a Disco on that Rig, or even the 1980's Neon madness!

Gaming Rig RGB Bling Narcissism is a sickness!
