AMD Inadvertently Reveals Ryzen 3 1300 & 1200 Details

If you were paying close attention to this morning’s announcement of AMD’s new Ryzen Pro SKUs, then you likely noticed something interesting: the non-X PRO chips all have the same performance specifications as their standard consumer counterparts. Specifically, both of the non-X PRO SKUs with existing Ryzen 5 & 7 counterparts have the same core counts, clockspeeds, and TDPs. And for the final 2 Ryzen PRO 3 SKUS? Well, AMD has inadvertently shown their hand here when it comes to forthcoming Ryzen 3.
With the release of the Ryzen PRO 3 specifications, AMD has now confirmed what we’ve been suspecting for the Ryzen 3 specifications for a while now. Ryzen 3 is a quad-core CPU without SMT, so we’re looking at just 4 threads instead of 8, albeit 4 threads without any of the resource contention SMT can sometimes cause. On which matter, it’s worth pointing out that AMD has already previously commented that Ryzen 3 will use the same die as Ryzen 5 and Ryzen 7, so we’re looking at 4 cores distributed over 2 CCXs, like the Ryzen 5 1400 & 1500X.
| AMD Ryzen 5 & 3 SKUs | |||||||
| Cores/ Threads |
Base/ Turbo |
XFR | L3 | TDP | Cost | Cooler | |
| Ryzen 5 1600X | 6/12 | 3.6/4.0 | +100 | 16 MB | 95 W | $249 | - |
| Ryzen 5 1600 | 6/12 | 3.2/3.6 | +100 | 16 MB | 65 W | $219 | Spire |
| Ryzen 5 1500X | 4/8 | 3.5/3.7 | +200 | 16 MB | 65 W | $189 | Spire |
| Ryzen 5 1400 | 4/8 | 3.2/3.4 | +50 | 8 MB | 65 W | $169 | Stealth |
| Ryzen 3 1300* | 4/4 | 3.5/3.7 | TBD | 8 MB | 65 W | TBD | - |
| Ryzen 3 1200* | 4/4 | 3.1/3.4 | TBD | 8 MB | 65 W | TBD | - |
Similarly, AMD’s reveal indicates that Ryzen 3 will have the same cache structure as the lowest-end Ryzen 5, the 1400. That means just half of the chip’s total 16MB of L3 cache is enabled. However each core still retains its full 512KB of L2 cache. Finally, this inadvertent reveal also confirms that TDPs for the lowest-end members of the Ryzen family will stick with the same 65W TDP as all but the highest-performance Ryzen chips.
Of course, it should be noted here that AMD’s accidental reveal doesn’t mean that the 1300 & 1200 will be the only Ryzen 3 chips we’ll see. Just like the Ryzen 5 and 7 only had a couple of PRO counterparts, it’s likely that the story will be the same for the Ryzen 3 series. In particular, Ian suspects a Ryzen 3 1300X will show up, but we shall see in due time…

So the consumer marketing department confirmed it was an "inadvertent reveal" and that they didn’t give their ok? Cause between all the stuff that was already known, it just looks like they didn’t care for that "leak"…webdoctors - Thursday, June 29, 2017 - link
Fantastic pricing, with R5 at $170, the R3 will likely be <$150, that's pretty great for a quadcore chip with decent IPC. AMD must be losing money on these if they have the same caches as the R5...Probably will be the new mainstream office PC CPU, and depending on overclocking, for home builders too...hopefully the mobo pricing is reasonable.

The cache is on the ccx - their most basic cpu building block.Outlander_04 - Wednesday, July 5, 2017 - link
AMD do not lose money selling chips with disabled cores .They will be paying GLOFO less for them.
Margins will be lower ,probably, but you would expect that with lower tier products

I think the big issue here has been missed.This may well be their first true single ccx per socket product. My guess is there are useful savings in a simpler interposer than the usual dual ccx zeppelin die.
Yes, that extra simplicity should greatly improve overclocking.
At that end of the desktop market, its all about price, and its a v competent 4 core, which amd can make very cheaply.
There is also a tie in with the zen/vega apuS.
A single ccx cpu is a precursor ingredient for Raven ridge etc. anyhoo. That apu will also be a single ccx cpu, but teamed with a gpu.
Its possible they preferred to just use the same die as the apu, and leave the gpu space empty.
If I am wrong, why the delay? It must be radically different to existing 4 core ryzens.

"AMD has already previously commented that Ryzen 3 will use the same die as Ryzen 5 and Ryzen 7, so we’re looking at 4 cores distributed over 2 CCXs, like the Ryzen 5 1400 & 1500X."I missed that bit it seems.
So the r3 is nothing new. Its still an 8 core w/ bits disabled & maybe some economies on 8 Mb of L3 cache on the zeppelin die, and use of unsalable bottom binned cpuS for little more than their l2 cache it seems.

I was actually logging in there to critique this critically against AMD, but looking at the prices of the i5 the R3 will compete with, if AMD keeps the price below $150 a chip they should clean up nicely.I would like to replace my FX6300, but the price for an upgrade of that magnitude isn't quite there yet for me, not since I can still play my most demanding games (Arkham series) at 60fps and run my DVR in the background at the same time. My 6300 was about $150 new, motherboard was just under $100. To stay at the same level of parts with the Ryzen it's looking like I'm going to be $400... it aint cheap being at the bleeding edge I suppose.
