AMD Confirms Key "Summit Ridge" Specs

AMD CEO Lisa Su, speaking at the company's Computex reveal held up the most important CPU product for the company, the new eight-core "Summit Ridge" processor. A posterboy of the company's new "Zen" micro-architecture, "Summit Ridge" is an eight-core processor with SMT enabling 16 threads for the OS to deal with, a massive 40% IPC increase over the current "Excavator" architecture, and a new platform based around the AM4 socket.

The AM4 socket sees AMD completely relocate the core-logic (chipset) to the processor's die. Socket AM4 motherboards won't have any chipset on them. This also means that the processor has an integrated PCI-Express gen 3.0 root complex, besides the DDR4 integrated memory controller. With the chipset being completely integrated, connectivity such as USB and SATA will be routed out of the processor. The AM4 socket is shared with another kind of products, the "Bristol Ridge" APU, which features "Excavator" CPU cores and a 512-SP GCN 1.2 iGPU.

buildzoidI'm gonna replace my 5960X with Zen if the performance is within 10% of the 5960X. To hell with intel's 1000$ and 1700$ CPUs.
What makes you think amd high end won't be a $1000 cpu? None of history would show that amd won't sell them for that amount. Remember the fx 51-62 all sold in that price range.

intel made it easy - since Sandy Bridge there has been close to zero performance increase in CPU department... so if AMD can match IPC with old Sandy bridge and pack 4, 6 or 8 cores - it can not only compete but win not only intels mainstream, but also HEDT and even newest - 2016. june HEDT - witch has recorded the least IPC performance gains and the most price gains (vs previous gen HEDT) in CPU history ever. so bbasicaly intels performance has stayed in year 2010 level (tough 2010 level intel smoked everything amd had..... till now)

If this is right: "Bulldozer has ~ the same IPC as Core2. So, Wolfdale +5% = Nehalem, Nehalem +19% = Sandy Bridge, SB +3% = Ivy Bridge, IB +11% = Haswell, HW + 3.3% = Broadwell."

Then we have: 1.05*1.19*1.03*1.11*1.033 = 1.4756 => 47.56%

And then, if AMDs 40% IPC gain stands, it will be 7-10%-ish behind Broadwell.

PS
That sure is quite a number of IFs... :D

Well, Intel has certainly languished, but there have been improvements. See: www.hardocp.com/article/2015/08/05/intel_skylake_core_i76700k_ipc_overclocking_review/4

Sadly, we're very much in the dark. We got a ballpark estimate of the IPC, but we don't know clock speeds, we don't know TDP, we don't know pricing and availability... we don't know jack.

Me's getting tired of Intel's insistance of 4c/8t on high-end consumer desktop CPU. I need more for rendering. (Without selling my body parts)

So, hopfully, AMD can come back competitive.

AMD was also very competitive at the time the FX 51 was on sale. ATM, they dont have that advantage. So even if Zen is competitive, they wont price it into HDET territory, simply because they cant afford to. If Zen isnt a massive success, then AMD is going to wither on the vine, and the 2-300 market is many orders of magnitude larger then the 400+ market, which is orders of magnitude larger then the 1000+ market.

They may very well have a $1000 lineup, using a 16 or 32 core CPU and quad/octo channel memory. But baseline 8 core zen will be competing against the i5/i7 reign, and I dont think AMD is stupid enough to jack up the prices higher then what intel has before they can take back some market share/ mindshare.

You're held back by intel's 4c/8t CPUs, but you didn't go for an unlocked 6700 that could give you an extra 20% through overclocking.

I never said the baseline would. I said history would say if AMD releases a top end chip they will price it as such.

If zen is competitive with the 5960X then AMD should be able to sell it for a lower price and make up the difference simply in number of sales. There are still a lot of us AMD Loyalists that are waiting for the upgrade.

Except that the new intel chips are already hitting the market. That leaves intel the ability to mark the "old" 5960x's for peanuts.

Calling dibs on your 5960X if that is the case. I won't mind a 2nd hand Octa core.

The Athlon X4 845 which uses Excavator cores at 3.8Ghz turbo has a score of 1,775 on Passmark single thread performance.

Assuming the same clocks 40% more should be around 2,485 which would put it in second place behind Intel Core i7-4790K with 4.4Ghz turbo frequency (2528 score).

Edit: But then again based on those numbers, Excavator is only around 15% faster on single threading benchmark than Steamroller, but yeah, full 30% more than Bulldozer.

Man I'm so stoked to hear this and so longing To go back to AMD, I really hope this new chip can deliver and I'm sure it will ;)

Don't forget to double the number of cores...

Not that I feel comfortable spending $1700 for a CPU, but if you look back in 1993 when Intel released the Pentium 66MHz cpu they priced it at about $1000. Looking at the price of inflation, we're very close to a $1700 CPU back then. Technology has gotten CHEAP compared to back then. Thankfully scale of the industry keeps price relatively low on cutting-edge technology.

Now AMD, come on....force intel to price products lower. I want that 10-core beast, but I want it at $900. ;-)

Yeah but I am talking about Single thread performance (one thread active) which makes it easier to see the IPC performance.

I purchased the CPU during severe Intel CPU shortage in Canada. Nothing else was available. Besides, I'd rather go for 65w cpu. My build is tiny as hell.

Yep I misread your post you are correct.

If they offer copious amounts of PCI-e lanes, combined with IPC better than Haswell, I'll seriously consider an AMD CPU for the first time ever.

Im very curious, just love this bold (looking) step they took with this.

If its good, I might just kick my 2600k out for it, the processor is still fine but that thing sounds sexy

AM4 socket has all of my attention! Being able to take either a CPU or APU in the same socket/motherboard is going to be great!

Think of it. Someone could start a build with a reduced budget starting out with the best board with an APU then buy the monster CPU and discrete GPU as the budget allows. Win Win!

There is a good chance they will. 990fx has 38 PCIE lanes, compared to z170's 20 lanes, and x99's 48 lanes (40 from cpu, 8 from chipset). now, AMD is still 2.0, but the 800 series similarly had more lanes then intel did. I wouldn't be surprised if this carries into AMD's next chips.

Was just checking more of those Passmark numbers and even the Excavator cores looks to be very good, the thing is at least on that benchmark whatever AMD uses as the equivalent of Intel Hyper Threading seems much more effective, the AMD number of logical cores really seem to increase the performance as if they were physical cores unlike Intel ones.

Based on Athlon X4 845 chip, the theoretical score if it were 8 cores (2 logical per physical so 16 logical) should be around the 21,000 mark, taking in account Core I7-5960X has 15,982, Zen should destroy it with numbers close to 30,000 if AMD claims are true, only problem would be if they can maintain an acceptable TDP for such high amount of cores.

Also not sure if when referring to Zen they mean 8 physical cores or logical, in that case the numbers should be more on the 15-16,000 mark which is still good.

Edit: Just looked at some articles, they mean 8 physical :O, looks like the CPU price wars begin later this year, also numbers should probably be a bit lower because it seems at least the first announced Zen chip will run at lower frequency than 3.5ghz which I am basing on.
