AMD Ryzen 3000 series CPU with 16 cores leaks

[HEXUS]

The engineering sample spotted offers base/boost 3.3GHz / 4.2GHz frequencies.

hello! Now it's getting interesting. How many PCIe lanes?

AM4, so the same as before. However, with PCIE 4.0 manufactures could split some for new boards.

[Tabbykatze]

What is impressive is that 7nm Zen 2 has squeeze 4.2GHz on 16 cores onto the AM4 consumer platform.

That is a feat all by itself, no fancy crazy new socket changes, no ridiculous hoops to go through, all indications is just drop in and off you go.

This puts high core count multi core processing for budding devs/designers closer into their hands at a great price.

Man, that is what is cool.

hello! Now it's getting interesting. How many PCIe lanes?

24 PCIe 4 still (4 for I/O chip, 4 for SSD (hopefully with a 2+2 option for 2 SSDs), 16 for GFX.
PCIe 4 might only be available on the top end motherboards. Some mobos might come with PCIe 4 -> 2x PCIe 3 switches.

Rumour suggests that you may additionally be able to trade SATA lanes for PCIe lanes with these CPUs, although that will surely be a function of the motherboard's hard wiring of features.

It also might be a chipset feature rather than a CPU feature - rumours are always vague. I wouldn't make any decisions based upon them.

My 1700X has been rock solid in games and 3D applications, will be definitely looking at the 3700

In the run up to every single new AMD release, rumors have consistently been hugely, excessively optimistic on this board. They are then discussed amongst some members as if they are fact. I don't know about other boards because I don't bother visiting them.
The only exception (that more or less proves the rule) was the original Zen. I recall the rumors being bang on the money.
This was the case with everything since bulldozer (20% more IPC than Core2, much higher frequencies. Reality was a CPU that was complete rubbish, had lower IPC than even AMD's previous generation)
With that in mind, I call BS on the prices or the core counts. Unless Zen 2 has some serious performance problems (which I actually severely doubt - Zen 2 looks to be AMD's 4th largest ever generational jump after Zen, the original Athlon and Their first 64 Bit CPU's)
AMD pricing for both their GFX cards and CPU's has been "slightly higher value than equivalent Intel" Every time pricing before release has looked insanely good value, it's either been that the price rumours were wrong or the performance was appropriate for the price - i.e. dismal.

I am following Zen2's news with great interest but we need to keep our expectations realistic.

But if we don't get our hopes up, how can we ever have the usual bitter disappointment?

I think it is partially because people don't just want to see something competing with Intel, they want Intel to get spanked for their business practices and stagnation. And that leads to overenthusiasm and hope that AMD are going to get all spanky with leather and whips and so on.

[flearider]

well I did say I wouldn't build another gaming system .. ..
but the other half does need an upgrade ..so I will kindly give her mine and have to build another with a 570 board and a 3700 chip .. dam what a shame ..

Well I think at least one of the rumours has been blown out of proportion.

The AVX native width has apparently doubled, which should bring that on parity with Intel. For workloads that need it, that should be a huge boost, and sure enough there were rumours of increased IPC on scientific workloads which some have taken to mean huge increase in IPC generally. It isn't, though the increased cache bandwidth needed to feed those floating point units might help.

I'm predicting that it will still suck at PiFast, but as soon as other meaningful benchmarks and prices come out I will know whether I get one of these or a another 2600X. In the meantime, Amazon have the 1700 for £140 so there are some real bargains out there.

Personally i just look in the mirror.

Speaking of cache AMD have said the number of cache entries per core have increased (from 2048 to ???), i assume that means the cache size has increased but as I'm a little unclear if the number of cache entries is related to size I'm not entirely sure, would you or anyone else happen to know?

I'm just waiting because this system I've been hanging onto in my "work" pc is beginning to show it's age badly. Xeon X5670 (was a X5645) with 24 gigs ram and a 480 gig boot ssd with 6 tb hard drive space. GFX are currently a Radeon R9 270X but some sort of second hand upgrade will come it's way shortly - Radeon because I get slightly more OpenCL bang for buck with it and I don't really need CUDA.
I will then cascade this down to music pc which is currently a Phenom 965BE...and so forth. Music pc currently on Win 10 X86 as well as a synth needs 32-bit to work...but I might have a way round that....
Then gaming pc and other working pc's may get upgraded. Blimey some work there. A Ryzen of some sort with 8c16t will be the plan and perhaps a nice nvme boot ssd

The Ryzen 1700 has been absolutely fantastic, for me. Running multiple virtual machines in parallel, all talking to each other, in a home development environment has finally become a reality.

If the 3700 improves the single threaded performance (and ups the ghz across all cores) and increases the core count, it's a no brainer to upgrade.

[Tunnah]

I don't think there'll be the 20% IPC improvement, but I genuinely don't care. If they come in at ~10%, even 8%, I'll be happy, because overall, if the pricing stays true, you're looking at an 8c/16t part for ~£200 and that is just insane. As long as it goes up to 4.6-4.8ghz, it being ANY sort of improvement of what has come before and it'll be worth it.

I'm so genuinely excited for this! Moving from a quad core from 2011 with DDR3 1333mhz to 8 cores and DDR4 3600mhz, no more fiddling around with benchmarks trying to figure out which settings are chewing my CPU rather than my GPU

[simonpreston]

you're looking at an 8c/16t part for ~£200 and that is just insane.

That is available now if you so wish.

The 1700s (also 8c/16t) now down to ~£140 - now THAT is insane, for what you're getting.

[DanceswithUnix]

Not surprising to see these cheap Ryzens topping the Amazon best seller ratings.

It is slightly surprising to see the FX8350 at number 8, but if you have an old Athlon/Phenom II board kicking around then for £55 it is a pretty decent upgrade.
