World's fastest gaming CPU - Broadwell with Iris Pro

[TheProgrammer]

I've been waiting for Crystalwell on the desktop for a long time. I've been wanting to rid my system of AMD/NV garbage like it's 2001 all over again and we said goodbye to sound cards. For 1080P gaming, Iris Pro is more than fine for my needs unless I decide to build for VR. I think soon, many more people will be thinking the same thing.

Especially since the Broadwell 5775C is the fastest CPU for dGPUs as well. This is how Nvidia in particular will go down, as everyone buys these Iris Pro desktop CPUs due to the L4 cache advantages- and they stay for the surprisingly decent 1080P performance.

I've also been wanting to see how that 128MB would affect dGPUs and now we know.

"The gaming plot tells a similar story, but here, the 6700K is in the running for the fastest gaming CPU on the planet—and it would've won, too, if it weren't for the pesky Broadwell 5775C and its magic L4 cache. The 6700K improves on the 4790K by a tad, but the 5775C upstages it with a freakish string of gaming performance wins, even though its prevailing clock speed is ~500MHz lower."

Overclock a 5775C to 4ghz, stand back, and watch out. It'll be a monster.

Bring on AMD's HBM APUs. Both that and these desktop Iris Pros are going to change the game bigtime. Big problems for Nvidia ahead. Everyone from guys like me who want to use an iGPU, to those who want the ultimate gaming rig will be buying Iris Pros and then adding on a 980Ti/FuryX. Eating up a lot of low to midrange sales with Iris Pro.

I'm going to verify that the 5775C is receiving DX12/Vulkan drivers, see what GT4e has in store over the 5775C- then ordering one of these.

Anand's review is showing Iris Pro to be around half as fast as "entry level" discrete GPUs, and around 1/3, or perhaps 1/4 as fast as my 4 year old HD7850. Still not quite there for me.

The next iteration of Iris Pro might be though.

The 1600 ram was probably hampering Broadwell's igp quite a bit.

Power and transistor budgets will always mean there's a place for discrete GPUs.

I think Intel is wise to have large iGPUs (GT3e, GT4e) for niche products.

But for the vast majority of people a GT1 is probably overkill already.

This makes me wonder about the purpose of GT2?

Power and transistor budgets will always mean there's a place for discrete GPUs.

For me, I would just take a Core i5 laptop chip with GT1 for everday usage.

Then, if I needed extra graphics, I would make sure my laptop had Thunderbolt 3 and then connect an external GPU.

Iris Pro is very bad for the money, $100 cards can demolish it in many games,

witcher 3

GTA 5

BF4

and power usage is not a big win

I don't think using Intel IGPs on desktops is going to start making sense for gaming any time soon.

as for the CPU side, Skylake can run at higher clocks, with faster memory and compensate easily I think.

I don't think using Intel IGPs on desktops is going to start making sense for gaming any time soon.

Except for the massively growing field of E-Sports, where the graphical requirements for many games (League of Legends in particular) is pretty low.

What ram did they use with Broadwell?

Looks like 1866? Wonder if anyone will do some memory scaling with the newer Intel IGPs?
7850K had 2400 ram and the IP6200 was right with it.

Skylake GT4e should be quite a bit faster than IP6200.

it's overpriced for any game.

SC2 and CS are Esports right?

playable, sure, but for the money it's quite bad, also CS on max settings would probably look worse.


and that's not even a 750 ti, just the 512 cores version, the soon to be released gtx 950 will be a winner for Esports, not any Iris Pro.

 

[LTC8K6]

9th gen GT2 Skylake should be a little faster than 8th gen GT2 Broadwell.

I wonder if that follows with GT3 and GT3e, with the Skylake version faster than the Broadwell version?

[LTC8K6]

Come to think of it, we are unlikely to see these Broadwell IGPs any time soon, and we can already buy Skylake I5 chips at Newegg.

The point of Broadwell desktop for an enthusiast is not the iGPU, it's the L4, period. Posting graphs of any iGPU getting killed by a dGPU is a Captain Obvious move.

Exactly, I have been arguing this with the AMD APU crowd forever, and the same argument goes for intel. At least with intel you get state of the art CPU performance as well, but at a much higher cost.

A) iGPUs suck for AAA gaming until Intel equips mainstream i5s and i7s with GT4/max iGPU spec

Until you can get a 8770K with a 256MB cache of L4 and 1000 EUs at $300 dedicated GPUs are going nowhere for 60FPS AAA gaming with all the eye candy.

Problem is if that iGPU gets too large the CPU is going to throttle down to make TDP.

not very obvious

OP states
"I've been wanting to rid my system of AMD/NV garbage like it's 2001 all over again and we said goodbye to sound cards. For 1080P gaming, Iris Pro is more than fine for my needs unless I decide to build for VR"

when Iris Pro is delivering half the framerate of a $100 nvidia card (from 1 and half years ago) in some games...

and almost every single Iris Pro review ignored $100 cards which should be the real target for a decent enough IGP for gaming, and mislead people into thinking they are any good for the money.

the l4 cache helps but it's not enough to beat skylake at the same clock for most games, and now you consider that Skylake can run at much higher clocks on average and...

that's gaming average for quite a few games,

now in some specific cases the l4 can help more, and if you already have a nice z97 board and not a 4790K, sure it could be a nice option;

I think it will take a lot longer than an 8770K for it to be viable, Intel is not going to crazy with the die size for $300 CPUs, skylake is only 120mm2 and up to $300+
(I know price is not all that related to die size at this point, but still, going for 1000 EUs and 256mb l4 will take a lot)

Same could have been said for FPUs. Actually for all the logic that is now included on a SOC.

As long as intel is charging a whopping $3 per square millimeter for their anemic graphics silicon, they will never be a serious threat to discrete cards.They are just wasting silicon and making themselves more and more obsolete by the day. Jesus, even the outrageously overpriced Titan X only costs about $1 per square millimeter of gpu silicon, once you subtract out the cost of the other parts on the card.

I really am not sure how you get that Iris Pro is a bad value for the money based on a comparison to a $100 discrete GPU. The Iris Pro on Broadwell doesn't cost $100 more than Devil's Canyon or 4770k or 6700k. And it beats or meets the performance of ~$70 discrete cards. And it appears to do so using less power than the discrete solutions.

It may be a niche solution that doesn't meet most people needs, but there does appear to be a market for the product. The fact that it isn't a good value for YOU doesn't mean it isn't a good value for anyone.

For the kind of person who wants a top flight processor for work but might want to play SC2 every once in awhile, it's perfect. Sure it might only pull 60 FPS on Ultra while a GTX750 gets 90, but the kind of people who would be interested in using Iris Pro likely aren't using a 144Hz monitor anyway.

if you are one of the rare few people who needs core i7 performance and want to game with pretty low quality, sure it might work... but for gaming a cheaper CPU + discrete card for the same money is way, way better, and for the non gaming ones Skylake i7 is better.

No one read what I said in my OP or checked my link. This was posted in the CPU section because Broadwell 5775C is faster than Skylake i7-6700K with the same standalone video card! That's the point to the dramatic thread title, this is a big deal.
Iris Pro 6200's 128MB Crystalwell cache made it so.

While being a 3.3/3.7ghz chip. 6700K is 4.0/4.2ghz.
Get that 5775C up to 4ghz and watch everything on the market be completely obliterated.
This is all horrible news for everyone who has been hating on APUs for years. No one in their right mind who is buying a new CPU for gaming would buy a CPU without Crystalwell. These results are on a 3.3ghz Broadwell.

And half the people who buy those for adding on video cards will soon only be adding a standalone card for VR. Intel (and probably AMD with HBM) are going to sweep the low to midrange market since it's so good for both integrated performance and for discrete GPU performance.
But that's beside the point and was inevitable anyway.

I decided based on these results I'm building with the fastest Skylake 128MB Crystalwell chip I can get my hands on.
