x264 on Nehalem

[puffpio]

http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3448&p=18

These benchmarks cite "We're reporting results from the 0.59.819 version of x264."

I'm not familiar w/ that version numbering (i'm more familiar with the revision /commit numbers)

is this a recent build? this is w/o the Nehalem optimizations right?

[Sharktooth]

r819. that was pre-production hardware. the final results may vary (expecially in a better way)...
look here: http://forum.doom9.org/showthread.php?p=1209478#post1209478 and here: http://www.ntcompatible.com/Intel_Core_i7_Reviews_Roundup_s121605.html

[Dark Shikari]

I already have a Nehalem performance patch ready; I just can't commit it until official release :cool:

[mikeytown2]

is this official enough?

[Sagekilla]

By official, I believe he means a "hard launch" where it's actually available for consumers, not a paper launch like they just did. That, and he may be under a NDA where he wouldn't be allowed to release it until a specific date.

[Blue_MiSfit]

You're telling me that the massive performance increase that's being reported by hardware sites doesn't even include Core i7 optimizations?

I can't wait :D

I guess it's time to start thinking about new encoding servers :(/:)

~MiSfit

[Sagekilla]

Well, they used an x264 exe that's what, 200 revisions old? I'm sure by the time Nehalem rolls out proper we'll have some.. sizable gains in speed.

[Snowknight26]

Supposedly the NDA was lifted today. Hope its true. :\

[Dark Shikari]

Supposedly the NDA was lifted today. Hope its true. :\It was? I have no idea when mine ends... :p

[tph]

Yeah, it's lifted. There's a ton of Core i7 reviews (http://www.xtremesystems.org/forums/showthread.php?t=206624) up now as well.


*edit* Oh, and since the NDA is lifted, do you have any performace comparisons for us? :D

[hajj_3]

Yep, NDA ended around 36hrs ago, go submit the nehalm patches:) I wanna see some proper benchmarks with the new cpu's.

[Dark Shikari]

Yep, NDA ended around 36hrs ago, go submit the nehalm patches:) Already done (http://git.videolan.org/?p=x264.git;a=commit;h=a5ac6a5b8688915553fe6fccee09f1272f3788ac)... I wanted to do the pminpos patch as well but there are still some issues with that one, like the fact that it doesn't actually work properly.
I wanna see some proper benchmarks with the new cpu's.How about this? (http://i38.tinypic.com/161nvdh.png)

[hajj_3]

not bad:)

Would be good to see benchmarks in fps of High Profile Level 4.1 with 2-pass unrestricted profile and do 1920*1080, 1280*720 and 640*352 resolutions to give a real impression how much faster it is for bluray and for 1080i mpeg2 and 1080i mpeg4 tv encodes.

[poisondeathray]

Just curious about the mechanics of the new patch; does it use the new SSE4.2 instruction set, or some other aspect of the Nehalem architecture? or are the speed gains from 4 extra logical cores? or some combination of factors (probably) ?

Thanks

[Sharktooth]

SSE4.x = Pile Of Crap (at least for video encoding).
The speed advantages are almost all due to the improved architecture and maybe the new hyperthreading.

[saint-francis]

@DS:

Overall speed improvement with Nehalem vs Penryn at the same clock speed is around 40%.

Are you still standing behind this statement? If this is the case these CPU's are going to essentially revolutionize the way we use X264. Could you post some more real world comparisons?

[Dark Shikari]

I don't see how its that revolutionary; new CPUs are supposed to be faster, aren't they? :p

[cogman]

I don't see how its that revolutionary; new CPUs are supposed to be faster, aren't they? :p

No Way!! New cpus are supposed to be hotter and more clunky. This Idea of faster and cooler is unheard of! (yes, im being sarcastic)

Whats amazing is the Size of the increase with nehelam (in the case of encoding) ~36% faster then the older penryn.

Though the speed increases aren't uniform through all applications (as they rarely are) But in some cases I do feel somewhat disappointed in the increase.

[burfadel]

Look at the difference between a Pentium 4 D (dual core) and a Core 2 at the same clock speed, there is no comparison! I think at times Intel understated the performance benefit of the Core 2 just so the P4 wouldn't look so bad! Even in single core mode, the Core 2 is significantly faster. It was funny when they were first released, a Core 2 E6600 at 2.4ghz could out-compete the P4EE at 3.8ghz! So 40 percent is not an impossible feat :)

[Sagekilla]

It's all part of Intel's Tick-Tock they've been doing ;) A Pentium D --> Core 2 provided close to 50% boost in performance, and now they've done it again for Pernyn --> Nehalem. That's even ignoring that Pernyn offered a speed bump over Core 2 as well.


I have to say, that's pretty amazing to pull off a close to 50% speed improvement generation after generation.

It seems like on average, nehalem has slightly higher latency and lower throughput. Then again on the specific ones that matter I suppose this doesn't really matter.

[Dark Shikari]

It seems like on average, nehalem has slightly higher latency and lower throughput. Then again on the specific ones that matter I suppose this doesn't really matter.Latency is roughly the same for everything that matters, and throughput is twice as good for all the major SIMD instructions (add, sub, etc).

Many 64-bit ops are faster as well.

ah that does remind me... (and a bit OT...) did anything get started on win x64 asm, or is that still on hold until someone can donate a box?

[Sagekilla]

Once I get a job I'll gladly donate some money to help get a 64-bit box. I'd love to see 64-bit support, especially since I'll be moving over to x64 for the full addressing space ;)

[akupenguin]

Still on hold.

Oh, the developers already have 64bit boxen. What we don't have or want is win64.
Acceptable solutions involve either ssh into someone else's win64 box (so I don't have to deal with administration or extra hardware or reboot), or some kind of VM (which I have no experience with).

[LoRd_MuldeR]

Oh, the developers already have 64bit boxen. What we don't have or want is win64.

I understand very well if you don't want to go Vista x64.

However I guess you currently have Windows installed on your machine, at least for testing x264 on Win32. Most likely you are running WindowsXP, right?
So why not go WindowsXP x64-Edition then? The Look&Feel is exactly like "normal" WindowsXP, driver support shouldn't be a problem and it runs rock stable (believe me).
Unless you run some x64 programs, you won't even notice the difference. And if you need to run x64 programs you can do so.

Also my offer still stands: If anybody could provide me with some instructions on how to set up the SSH thingy properly, I'll do so ASAP.
I can't guarantee that my machine is up 24/7, but I could keep it running longer on request, even when I'm not at home...

In the case of ssh into a win64 environment, I might be able to provide something like that very soon. I'll be upgrading my main system to a new platform soon, so I'm relegating the old parts to a server, which will run 64-bit XP in that case.

After that, it's a simple matter of setting up ssh for you over the network.

or RDP... that will eat more bandwidth but lets you do more things than the half-ass windows console... unless you can properly set up a ssh daemon on cygwin or msys/mingw.

This is what I use for RDP connections to my box, works great!

I've used OpenVPN (http://openvpn.net/) or Hamachi (https://secure.logmein.com/products/hamachi/vpn.asp?lang=en) to take care of the tunnel, depending on the client I was setting it up for. You can also follow this guide to make your own tunnel

I've been saving up for a new system; And for my next system i'd like to go back to a dual-CPU system / workstation. I've tried dual-core/quad-core, but it isn't as fluent as my former dual Xeon.

I've seen dual Nehalem (i7) boards on display, but none has arrived to market yet. But what i found is that many of these dual-boards seem to have a NUMA-configuration. Since Nehalem (i7) has it own on-die memory controller, a NUMA configuration makes sence; In this case each core can have direct access to memory, as opposed to the other option that 1 CPU has to "go tru" the other CPU to get to the memory.

I have no expiriance with NUMA-configurations, and so my question is this: Would a system like NUMA have advantages to x264 (would NUMA have a benifit at all ? ). and would "it work" by itself, or is a special compiled version be needed to make use of this ?

NUMA: http://en.wikipedia.org/wiki/Non-Uniform_Memory_Access

(I could allways simply "virtualize" a 2nd PC for my encodes, and keep working on the other "virtual PC" ... but more power is better in encoding-world :p )

More mubench results (http://akuvian.org/src/mubench_results.txt).
IMO easier to read than Dark Shikari's table.

I've been saving up for a new system; And for my next system i'd like to go back to a dual-CPU system / workstation.Same here, my problem is, which one would be faster for x264 encoding? Given the choice between a dual-cpu system with 2 Xeon E5405 or a nehalem system with an i7-920, which one would be faster?

I suspect the Nehalem, but who knows.

I'm waiting for the Xeon-version of the Nehalem's/i7's, so i can build a dual based on those. And those systems are going to be NUMA configured (expected is that all "more-than-one-CPU systems" will be NUMA configured, so NUMA awareness might be resonable to take into account).

[Dark Shikari]

Another patch coming soon: No change on A64, 0.3% boost on Core 2, 0.6% boost on Nehalem. Every bit counts. :cool:

[plonk420]

How about this? (http://i38.tinypic.com/161nvdh.png)

is this at the same clock speed?

[Dark Shikari]

is this at the same clock speed?No, the numbers were measured in clock cycles, so its independent of clock speed.

[Chengbin]

Wow, x264 on Nehalem sounds great! My old Q6600 must suck really bad now... I want one!

Unforunately I have to wait another 2 years to get another computer...

Keep up this good job! I like this.

[Sagekilla]

Haha, your Q6600 must suck? I'll take it off you :) To replace my good old Opteron 170.

@Dark Shikari: What instruction was improved that caused weight B-pred to have such a massive speedup?

[akupenguin]

paddw and punpcklbw got double throughput. Also biweight has unaligned input, and the cacheline split penalty was reduced from 12 cycles to 2.

[LoRd_MuldeR]

And now back on topic: Are all the patches for Nehalem (that have been made) already committed or are there some being tested still?

Unless I missed something, the patch mentioned here (http://forum.doom9.org/showpost.php?p=1210735&postcount=36) was not committed yet.

[lexor]

DS also said that they are holding one of the patches back because it has issues, possibly the same patch LoRd mentioned.

[burfadel]

CPUs can contain errors, its possible its a manufacturing/design flaw that may be rectified with a future stepping or bios microcode? update...

[akupenguin]

Not to underestimate the number of hardware errors that have been discovered by ffmpeg/x264, but I really don't think that's the problem. The phminposuw patch was developed and tested on a penryn, so there's been plenty of time for people to notice if the instruction didn't work at all.

so how much more do the x264 devs expect to increase the performance on the nehalem chip?
even some 'eyeball guesses' would be OK, if you don't know for sure.

Intel say 40% for massive multithread software. For same clock nehalem will increase x264 at 40% the performance.
