New details regarding upcoming GTX 780M

and....? bit more info please? lol

 

It was on a similar performance level, 940xm vs 26XXqm. The difference was, 9xx cpus can be overclocked freely, easily, which thankst ot it, completely outperformed 26xx cpus, even 27xx and only lost to 28xx. soundily.

Core i7 9xx cpus are still a great choice despite being so old.

The comparison between Ivy and haswell is still valid, as he mentions it will be a clock for clock performance increase. If both old and new gen share same clockspeed, it is obvious the differect architecture brings this extra performance at the same clockspeed.

I doubt they will push too much the envelope, it seems only very few of us consumers care for extreme performance.

 

1536 711 5000 256 160.

 

CUDA cores / core clock / mem clock / memory interface / 160.....?

now thats just mean out with it!

edit: 160 = memory bandwidth in GB/s!

 

Well thats the specs of the 680mx.... so the tdp would be higher.

 

Forget 4G Vram.

 

well we already speculated that the 780M might just be a rebranded 680MX inside a 100W tdp envelope, right? so that might just fit the bill

 

damn I want one of those babies

 

No 160 = TDP...

But yeah that *IS* the 680MX. Hopefully it can run within the 100W TDP envelope. But it's still not going to be anything uber significant over the 680m considering clock speed is slightly less. Memory clock should OC a decent amount though, but I think the limited GPU clock may hinder that performance.

 

But not according to Anadtech. AnandTech - Intel's Haswell Architecture Analyzed: Building a New PC and a New Intel

Improvements are mainly in power efficiency.

You kidding? Overclock the core to 1 ghz and the memory as far as it can go and you have a 680. The decrease in the core clock also suggests that they lowered the voltage to fit into 100W so it probably won't overclock as well as the 680m on stock voltage but that's what overvolting is for.

The only question is how hot will it run?

We don't know how well they managed to optimize the core for lower consumption so there's no point in speculating about TDP yet. We do know however that the 680m doesn't consume the full 100w so they did have some room to play with.

 

I don't know about that. If you compare 680m vs desktop 670, I can OC my 680m to 1GHz and 2400MHz RAM and against my desktop 670, it's still lagging behind by 20-30%. Same number of cores (1344), same GPU clock (1GHz), vRAM is 4800 vs 6000 though, but I can't see how that would improve performance 25% just because it's 25% faster vRAM. But maybe.

 

hm, u should probably check with meaker, hes the one always preaching how bandwidth-starved the 680m is, thats also why he oced his to 2700mhz via a pencil-ov-mod

Pencil overvolt wuttt???? I never heard about that lol. I knew his benchmarks were nuts, but didn't know he did anything like that. Why not just flash the vbios? Pencil tricks are oldschool

 

well apparently u cant overvolt the memory just by flashing a modded vbios, that just works for the gpu core so he studied the pcb diagram, singled out the specific resistor, applied some graphite using a pencil in order for the pcb to switch to a higher mem voltage and voila, he could get more mhz out of it

i know its actually kinda "old school", i remember the days of palomino/thunderbird/thoroughbred amd cpus overclocked by pencil mods

The article you linked says that Haswell is a new architecture...

"Haswell is so much more than just another new microprocessor architecture from Intel."
"If you're not familiar with the terminology by now a tock is a "new" microprocessor architecture on an existing manufacturing process."

 

Your 680m at those clocks is basically equal to a 660ti. The 680m is heavily bottlenecked by the vram. Can't believe I have to bring up the BF3 example again. lol
The 680m's core has 60% more performance compared to the 675mx but it only gets 25% extra performance.because their vram is clocked the same. With this new upgrade to 2500mhz ram the core will finally be able to shine. Clock rates of:1gh core,2750 would get the 780m awfully close to a desktop 680(Edit:with the proper cpu:4800mq overclocked to 3.9ghz on all cores) I don't see a reason why it couldn't be as fast. Same core + almost as fast ram.

Edit: I noticed your cpu is "only" a 3610qm. It bottlnecks the gpu in benches so don't expect to get it close to the dtop equal. dtops have significantly more cpu power.

"Although Haswell is *labeled* as a new micro-architecture, it borrows heavily from those that came before it."

They didn't touch anything mayor in it. Skylake will be the true new arch.

 

Just stop talking... Really... The 3610QM does NOT bottleneck a 680M even after overclocking... :rolleyes2: You're talking about a CPU that happens to be faster than the i5-2500. I doubt you've any clue how fast the 3610 is... It handles SLI 680Ms well enough.

 

in the end, it all depends on the benchmark really some are just more cpu-intensive than others.

Depends on your definition of "well enough." It'll bottleneck the crap out of sli 680ms in benchmarks, even on stock clocks. It's been shown that even a 3740qm will bottleneck sli 680ms in some games.

Other than that, he's right. The 3610 will end up bottlenecking a heavily overclocked 680m in certain benchmarks.

 

Says the clown. lol It is a well known fact that a stronger cpu helps a lot in benches and also in some games. If my 2670qm which is only 10% slower bottlenecks my 570m here and there than a 3610qm will most certainly do the same in cpu intensive games and benches.

 

first of all, both the claim and your writeup here are weird to begin with.. it totally depends on the app you are running. 3610qm will bottleneck in some stuff, and 680m will bottleneck in some stuff. If you are talking about games only, then there are games (SC2, BF3) that are cpu bound, and games (Metro 2033, Crysis) that are gpu bound. I really didn't check it carefully which bottlenecks which (except for the usage statistic, but that is pretty much the ballpark we are talking here about bottlenecking), but certainly they will bottleneck the other depending on the application.

 

Note my NP9570 review the i7-3610QM outperformed my desktop i5-3570k in CPU tests.

 

At stock maybe but who keeps a desktop cpu at stock? Anyway. I expect that a 780m overclocked to 1ghz + 2750-3000 memory(we don't know how far it can go) paired with a 3740qm with the 400mhz oc will perform like a desktop 3770k + 680(both at stock clocks). I don't see a reason why it wouldn't. Same clockrates on the same chips. The only thing that could cause a dif is the drivers but again I see no reason why mobile drivers would cause slower performance.

Anyone except the clown are welcome to correct me if I'm wrong.

 

You mean i7-4720qm

Sent from my YP-G70 using Tapatalk 2

 

True.

It's not 4720qm though. The haswell lineup looks like this:
-4930mx
-4900mq
-4800mq
Clock rates are the same across the board as the current ivy cpu's.

 

Oh yeah that's right, it's MQ now

In any case it all depends on the game. but yeah, CPU can have an impact for sure.

 

I only have my experiences to go on but from those I can definitely say that the people who tell you that the entry level quad is enough are mistaken. Some games can need up to an overclocked XM to run properly. Shogun 2 TW is one example.

Here's a little app that'll help increase cpu utilization: Timer Resolution « Lucas Hale
Just get the free version. Works great for me. Explanation on what it does: http://www.youtube.com/watch?v=_hcuYiqib9I

 

i can only say that my 1ghz OC on my xm cpu didnt really do jack squat so far as far as games and (most) benchmarks are concerned when compared to my previous 2860qm (that was with a 25% OC on my 7970M) the two most significant changes i noticed in pcmark7 and cinebench, which were both to be expected, of course

and please dont tell me now its only cuz i have a 7970M instead of a 680M judging from bench scores, i can definitely keep up with most users on IB and OCed 680M (no meaker, i wasnt talking about YOU here now )

 

Buy Shogun 2 gold pack! I guarantee it'll give your cpu a work out. You'll need a huge dual core oc for the game to work properly. Creative assembly were lazy and didn't optimize it for quads.

 

well as i said before, it all depends heavily on the program / benchmark / game that were talking about but to make a "general" statement, i dont think ill be needing to do any cpu upgrades for the next 2 years only thing thatll get me to buy a whole new machine is if the nextgen gpus wont be compatible with my laptop anymore so one more year is the plan with my baby, maybe even two, well see....

 

You have a lot of nice number in your sig. You should upgrade to some faster ram though. Kingston 1866mhz pnp?

Btw. I have this feeling that the next gpu's aka Maxwell and what ever AMD will call their next arch won't be compatible. there are a lot of changes coming next year. Cpu cores implemented into the gpu + gddr6. 2014's gonna be an exciting year.

 

corsair vengeance 1866 2x8gb kit is the plan! but that will have to wait a bit, since im in the middle of a move to a new city / new job, etc. maybe in a month or two its not like it will make such a big difference anyways

even if 780M/8970M wont be compatible with my machine, ill still enjoy it for one more year before going broadwell if they DO turn out to be, ill make it two years instead and put my money on skylake

 

Yeah I'm really looking forward to 2014 as far as technology. Between nvidia, Intel, and DDR4 and GDDR6, it should make for some spectacular advancements in overall PC performance. Not to mention where we'll be with SSD's.

 

and then we will again be bottlenecked by the crappy consoles of that time (the new generation which will use GCN based gpu and IB based cpu)

 

But at least we'll get good quality ports thanks to the cpu's using x86 and huge texture resolutions thanks to the 8 gigs of vram.

For your XM cpu faster ram does make a dif.

The 780m and the 8970m will be compatible with your machine. I was talking about the 2014 gpu's. I have a feeling those won't be with any of our current machines.

 

MXM 3.1 B is fairly new and already features pcie 3.0. Even a SLI or xfire mobile setup in 2014 won't be able to max pcie 3.0 x16 ! For single card machines pcie 2.0 x16 will still be enough at that time.

If there isn't a reason to change the factor then why would they change it. Just costs lots of money to develop.

It might change but I think it unlikely so soon.

 

ya, for sure we will get 780m compatible with our laptops, a rehash shouldn't change the connection after all right?

 

I was talking about 2014's gpu's. The 780m and 8970 should both be compatible with current laptops.

 

its not the mxm connection im worried about guys. since the 3.1 standard was just barely introduced in 2012 its not gonna change that quickly and its downward compatible to 3.0b.
what im rather worried about is the switchable graphics/vbios/system bios compatibility since that is the major culprit when doing unofficial gpu upgrades on a EOL machine.

As long as it can run on my 8170 I'm pretty jazzed about it

 

I'm already planning on upgrading in 2014 for many reasons:

(1) Intel Broadwell hexacore
(2) nVidia Maxwell (over 2x performance of Kepler)
(3) 4x (or more) SATA III ports
(4) DDR4 (yes it's coming) 2400?
(5) 4k screens (or likely higher res)

 

would ddr4 be already available for consumers in 2014? i thought theyd barely started prototype programs for servers this year...

 

Not sure about ddr4 (I think I read that by 2015 ddr4 will be in most new computers, so it's possible.) 4k screens won't be in gaming laptops by that point either, but I'm still really excited about Maxwell and Broadwell anyway. I'll definitely be upgrading to a new M18x (or equivalent) in 2014.

 

oh cmon, as if u arent already always on the bleeding edge anyways when it comes to highend rigs, even if its mostly just for reviewing and benching the crap out of the hardware

Sent from my Galaxy Nexus using Tapatalk 2

 

DDR4 should start to trickle in end of this year, and become mainstream by 2015, so 2014 would be a transition year really, so why not let Intel lead the way with Broadwell. Same thing with 4k screens. I guess I personally don't care for a 4k screen, just a 2K screen (2560x1600)!

 

Yeah, 1560x1600 would be perfect for 17-18" laptops, especially with how insane the 8xxm series will be. Can't wait

 

gOSH DARN IT! when did the laptop seen become the desktop scene lol.. Ive been very happy in the past having the best of the best for 6 months to a year.. now it seems every 3 months some thing better is coming out... geeeeeeeeeeeeez

 

Hey, at least you've had your rig for a while, I just bought mine and it's about to be outdated

 

It's always been the case. Actually CPU and GPU are only refreshed every year. If you buy with the next die shrink and architecture change, which is about every two years you will get the most longevity out of your machine. That's where I'm at. Bought 680m in June 2012 along with Ivy Bridge CPU, right at release, will get a solid year out of it before it becomes "outdated" or "obsolete" (lol). But the change to Haswell and Kepler will likely be less than 20% improvement, so no need to upgrade. But come June 2014, it will likely be a 100%+ improvement (probably more), and that will be two years. I still may be able to sell my NP9150 for $500-600 and put that towards a new $2k+ laptop.

 

Optimus works well now. Enduro is newer so it has it's problems still. I can imagine by 2014 Enduro will work well too. We shall simply see. If my M15x still works by next year then the next set of cards will last me a couple more years

By that time it will be time to move on!

I dunno HTWingNut. The 3.5 year 920xm can still crunch it's way through games matched with a single powerful card without bottlenecking it. I think if you buy the best components and spec then you double that time to a good 4 years before something becomes a major bottleneck. BF3 was the most cpu intensive I have played taking up to 85% of cpu load running at 3ghz across all cores. Considering it goes up to 3.3ghz on 8 threads well the chip still has life left in it. I guess though the 920xm was a huge achitectural change for it's time like the 8800 GTX was for it's time.
