Intel's 28 Core 5Ghz CPU is misleading at best

RadiatingLight

Some of this was mentioned at the end of the previous thread regarding intel's 28-core CPU, but it's not in the main post, so many more people will probably see it here.

 

Intel's 28-core 5Ghz CPU is nothing more than extreme overclocking of an existing Xeon Platinum 8180.

 

Quote

Intel's demo didn't tell the full story. Many in the press mistakenly assumed the new processor runs at 5.0 GHz at stock settings, but we carefully analyzed video from the event and spotted a few obvious signs that the processor was overclocked. Intel was apparently running some sort of closed-loop cooling that required insulating material around the tubing.

Picture of Intel's crazy cooling setup:

20180606_085740
 

This is an $850 aquarium water chiller which consumes 1200W and is supposed to be able to cool 1000L of water -- seems pretty extreme to me.

 

The VRMs for this system are similarly ridiculous, with 4x8-pin EPS connectors, 32 phases, and a massive heatsink with 4 fans.

finally, this CPU was also running on intel's LGA-3647 server platform, which all but confirms the fact that this is just a 28-core Xeon with an unlocked multiplier.

So in summary, Intel's 5-Ghz 28-core processor was nothing more than a feeble attempt to steal AMD's thunder in their announcement of a 32-core Threadripper CPU.

 

Quote

In the end, the incredible requirements for overclocking the 28-core processor, which requires hefty power and cooling accomodations, make it clear that most enthusiasts won't be pushing the limits of Intel's 28-core processor any time soon.

 

 

Additionally, it seems that someone working at AnandTech says that Intel took everyone's CPUs away:

So it is not a core i9?

 

Thats just sad.

 

I think everyone on this forum knew it wasnan overclocked chip that was also most likely binned

Was it to spoil Threadripper 2 a bit? Why not? If it was misleading at all depends on what claims were made around it, and I've not dug into that. For now, I'd regard this in a similar way to any LN2 world record reports, which is nothing as I'm not going to buy it any time soon. I'm also not going to get TR2 either.

in the future they might decide to put it into the LGA2066 socket if it can fit, but the system demoed was a server board, with 6-channel memory and an LGA3647 socket

I dont see how they can make it fit or work on LGA 2066, even if they do it going to take a while to do that when TR 2000 already has production samples. and Epyc 2 has lab samples.

would be a hard stain to rub off if it's really a smear campaign in hardware form, if it's really uncovered as such o_o

Marketing has always been a problem, both supplying and consuming. They want to make what they're doing seem better than the competition, being careful to give a certain impression that is not technically false, but isn't the whole truth either. Intel do it. AMD do it. Everyone does it. This is particularly important in halo products. Even if people never buy the things, you want to demonstrate what you can do, and people buy the low end thinking they get a related product.

 

Thinking about it some more, I think I'd like to see both Intel and AMD change course slightly on the HEDT zone. Rather than try to cram ever more cores into a single socket, just give us an affordable multi-socket implementation like the good old days, like the Abit BP6, or the last one I had was the Asus PC-DL. They were largely negated by the arrival of multi-core, but if you find it hard to put more cores in one socket, use more sockets. CPU cost per core should go down, at a more mild increase to mobo cost.

Everyone's going to shit on Intel for this, but it's not like AMD is any better. When they released Ryzen they cherry picked benchmarks it'd excel at, and real performance wasn't nearly as impressive. Same thing with their GPU benchmarks.

Their timing was... interesting.  They HAD to know that AMD had a 32 core TR2 out this week.  Why go through all the effort to show off a product that wasn't (5Ghz though) as good to begin with?

It does seem desperate and immature.

If anyone believed that a 28 core chip at 5GHz which could be cooled with normal method was going to be on sale when the same chip running at 3GHz costs $10K...


The VRMs had finned copper heatsinks with heatpipes which were larger than those used for the Pentium 4!

Showing what your product is good at is not cheating, Cinebench is a commonly used benchmark and generally a good estimate. Companies who do not show off how good their product can be don't exist for long.

Agreed.  Cherry picking some benchmarks for a product you are selling to make it look good is one thing.  Cherry picking a CPU, Motherboard, Cooler, Firmware to unlock it and not really intending to sell it (probably) just to shit on someone else's product introduction isn't.

Ok so not cheating when AMD does essentially the same thing? Showing off how good your product is by cherry picking is cheating though. As mentioned of course this was a halo product just to show off that they could get 28 cores to 5Ghz, but I think they shouldn't have shown it off at all after the Intel event if it's just a "hey look what we did" product.

True. Showcasing your product is something that everyone does

Go see the other thread and people were already telling that TR2 is DOA because of the 28 core part from Intel...

That's a win for Intel...

Cinebench is a well respected benchmark which many people use unlike standardized benchmarks like SPEC. If AMD demonstrates the performance of their new GPU in Superposition it is acceptable because it is a commonly used program.

 

If I show off how fast my car is by racing on a flat road on which the car's tyres are suited for (common scenario like Cinebench, Cinebench suits Ryzen well) it is more honest and reliable than attaching rockets to the car and launching it from an aircraft carrier launch system (Intel showing off a non existent product overclocked 60% and cooled with a 1000L cooler).

Epyc has 32 cores, the moon lander has 1 main core (maybe redundant systems), therefore my very Epic computer can land on 32 moons at once!

They most likely had this as a proof of concept and kept it back to use as a distraction should a competitor launch a potentially good system.

Cinebench is not a problem, remember the AMD guy from Bulldozer days who used to talk about how super duper the CPU was going to be before it came out? He completely vanished after the CPU's release, because everybody then knew how shit it really was.

I don't want to ditch on AMD specifically, this act of Intel is absolutely low. But they too have had their shares as far as dishonesty goes. Especially with their slides. Look at this, they cherry-picked the games the RX 560 performs better, then talked about efficiency as if it's more efficient than a 1050...

Little detail: AMD only taked about TR2 being up to 24 cores before their computex announcement, only then we learned it won't be 24 cores but 32 cores max, which happend after Intel showed off their 28-core system.

 

There was a time frame where we thought TR2 is 24 cores, Intel is 28 cores.

It's not clear if TR2 was meant to be 32 cores from the start or if it was a last minute change/reaction to the 28-core intel system.

They really misjudged how well the core would scale frequency wise, due to the IPC drop it could be slower than it's predecessor. Theoretically it was a great design by removing infrequently used components but simply failed due to it's poor ST performance (They probably just then demonstrated the MT cinebench). 

Regarding Bulldozer this is quite interesting.

It was beyond that. It was a very inefficient architecture, and against Intel it made no sense to buy. They had Sandy Bridge at the time, hell even the older Westmere chips made much more sense to purchase. They could be bought at decent prices second hand in those days.

AMD is notorious for misleading in slides. They did that with more than one gen of GPUs, but I like them for not being as greedy as Nvidia. I.E, supporting VESA's Freesync and not getting any money from it. In fact, my next GPU is going to be a Vega. I'll be taking out my 1080 Ti for an LC, and buying a very nice Freesync monitor. :)

You have to a be a bit of an idiot to think this CPU was 5GHz stock.

 

Obviously it's an overclocked processor and obviously it's on "exotic" cooling. But then again, it's Tom's Hardware.
