Haswell-E with DDR4 showed.

[StinkyPinky]

I think the new consoles will drive games to more than 4 cores so I really want a 6 core for my next CPU. Guess I'll have to start saving since the mainstream cpu's seem stuck in 4 core mode.

8C/16T
you really think that is required other than just bragging rights? Good for 10 years? LOL, nope. 64gigs RAM good for 10 years, nope
While there are a few that will utilize such a beast today, it would do nothing for most who will use it for gaming or general apps

I would guess that it will not be needed for 10 years yet. But we all will buy cause we can

It will also be $$$$$$$, not a good "bang for the buck"

It's a bet then, lets revisit this thread in 2024 and see whats what.

Moar RAM is always better.

Windows' automatic ram cacheing (and linux's) is extremely nice.

Also, 8 cores will definitely be nice for gaming.

Just disable hyperthreading and then dedicate one core strictly for interrupts and mouse polling and background processes and you have as close to a latency free system as you can get.

I really wish hypterthreading toggling were not all-or-nothing and you were able to disable hyperthreading in all the cores where you would park the latency sensitive threads and then leave hyperthreading on for the threads that aren't latency sensitive.

Also, emulator enthusiasts running software rendering would love the extra cores as well.

I wonder what price premium will we see with DDR4.

Also with 2133 DDR4 can we expect same cl 9-11 latncies like DDR3 has ?

Default DDR4 2133 will most likely have a CL rating between 13 and 16, and more towards 16 than 13. I expect CL15 and CL16.

 

[NTMBK]

Apparently we shouldn't worry too much about memory size shrinking.

http://www.fudzilla.com/home/item/32504-intel-haswell-ex-and-ddr4-showcased

Intel used the IDF stage to introduce the Ivy Bridge E high-end processors and roughly a year before the next update we managed to see the demo of a Haswell EX. It was a memory demo, a system filled with twelve 16 GB DDR4 memory modules.

 

[seitur]

And 16GB per stick is not max. There will be at least 32 GB sticks in future.

 

[MisterMac]

Holy Shit.


If the ram size grows exponentially in the general consumer market - won't it mean OS\Engines can cache many more things for longer times, increasing the speed of everything exponentially as well?

No more HDD loads, at all for entire games.

Yeah. There will have to be work done in field of caching. This can lead to many nice opportunities, possibilities and performance increase.

Of course in the end it all depends on DDR4 price per GB. if it will be low or if it will drop fast, then end-users will buy big amount of RAM and then OS and software applications will use caching much more because there will be wide install base with lot of RAM.

It is more about availability and affordabiluty than about pure technological possiblities.

 

[CakeMonster]

There might be some ramping up, and the manufacturers might try to charge a premium, but to my limited knowledge I can't see why we would not get plenty of DDR4 rather cheap within months of mainstream DDR4 chipset launch.

 

[exar333]

I like to see a good 30-50% gain when I upgrade. I saw a great increase from 920 -> 3930. I am hoping to see some decent IPC gains along with a few more cores/threads. This looks solid, plus DDR4 will be nice (expensive) but nice.

 

[Ajay]

Hmmm, I feel better about an 8 core HW-E hitting at least 3.4GHz (stock) after seeing this: E5-2687W-v2-25M-Cache-3_40-GHz

 

[tweakboy]

Everyone settle down Haswell E is 1 year and a half away. The 8core version at least.

2014 if lucky summer of 2014 ,,, just a guess.

THeres 20 core CPUs Why dont you get that. Cuz you dont need it nor have the money. waiting for 8 core from a 6core ,,, I promise youll see no difference if your a gamer or regular user.. thx gl

 

[wand3r3r]

Pair that with 4k and it'd finally be something kind of exciting.

Why is it 150 W TDP? Since it's 8C/16T @ 22 nm you'd expect it to have max two times the TDP of a 4C/8C 3770K (which has almost exactly the same clocks). But it has more than 2x77W = 144W TDP, despite not having any iGPU which the 3770K does. Being an Xeon I know there are some differences compared to the 3770K (larger cache etc), but still.

Probably several factors: aggressive turbo for the workstation SKUs, more PCIe lanes, 1.5x the L3 cache/core, QPI link for 2P, higher supported memory speed (1866 vs. 1600 for DT CPUs). I'd also guess that the RDRAND implementation would be much stronger than in the DT models. And the server SKUs likely have more of a safety margin in the TDPs. Those little things add up.

Yes, I'd imagine the L3$ to be a major contributor, but there are a variety of server centric circuits which are disabled (non-existent?) on the DT model's die.

Well for one 2x77W = 154W TDP

And for another the TDP doesn't mean that the CPU will consume exactly 150W(or 77W) under load.

I stand corrected, 154 W TDP it is. Typed too quickly and was too tired... :whiste:

But still, normally they don't specify much higher TDP than needed. There should of course be some headroom, but that should apply to the 3770K too.

Also, I guess the iGPU is quite a big part of the TDP for higher end mainstream desktop CPUs like the 3770K nowadays. Something the Xeon does not have.

LOL! I totally missed that D'oh!

"DDR4 Memory Will Remain Expensive Until Late 2015"

"In its first 1.5 years on the market, DDR4 will be used for mainly for servers as well as high-end desktops, which will let it capture around one quarter of commodity memory market. Starting from Q3 2015, DDR4 will be adopted by client systems based on Intel Corp.’s code-named Skylake, which means that the pace of the adoption from that time will depend on the speed of Skylake’s ramp up.
[...]
According to IHS slides demonstrated by Intel Corp. at IDF, initially 8GB DDR4 RDIMM will cost around $90, but eventually it price will reduce to around $50 three years after the launch."

That math is faulty. The E chips don't have a iGPU and so you should expect the wattage to be lower than 2x77w. Most likely 130w or so, when you factor in the extra cache as well.

 

[dave_the_nerd]

Nice. The 8 core would be great for posting some nice benchmarks, but for a guy like me 8/16t is such overkill, even my enthusiast itch doesn't crave something like this to scratch it.

Agreed.

Somewhere along the line, my typical workload went from being GAMING!!!11!1!WTFBBQ to being crap I could do on any old 2C/2T CPU, even a low-voltage one, as long as it had the right software and a willing internet connection.

 

[tential]

When you look at all the people ditching desktops and moving to ultrabooks, you can tell that most people can get by with shockingly low CPU requirements.

I'd hazard : C2D E6600 w/4GB and a decent hard drive is fast enough for 99% of all worldwide computer users to do common tasks : web, youtube, email, word, angry birds, solitaire.

My Penryn mobile laptop is all I use with 8GB (Upgraded from 4GB this year) for the most part. I have a 4770k and rarely use it.

This is only remotely interesting to me due to DDR 4. TBH, I'm more interested in whether Baytrail - M is faster than my penryn, can fit in a ultraslim profile (3-4 lbs tops) and last 12 hours.

Uh??

sounds sweet but, ... wtf? how do you do this on Windows?
