Intel Xeon Question

I'm not sure how you got that more threads = less memory requirement. The graph shows that with the least amount of allocated memory (32mb), the completion time penalty becomes progressively more severe with a larger number of threads. The data is also a valid comparison for thread scaling -...

Intel Xeon Question

This document from the NIH suggests that performance in 64-bit Gaussian09 for Windows going from 1->2 processing cores increases by about 1.8x, and from 2->4 cores it increases by another 1.8, but from 4->8 cores it increases by only about 1.5x. The test wasn't run with 6 cores. This message...

Intel Xeon Question

While you have a point, there is no need to be rude about it. I remind you in my first reply I stated this "Please also note that I only quote one benchmark. I haven't done more in depth testing. Depending on your application, LGA 2011 may be worthwhile, but with the information provided, I...

Intel Xeon Question

Indeed, there is only the Xeon E3-1240, which is an LGA1155 Quad Core part at 3.30GHz. The Xeon E5-1600 series of LGA2011 processors only supports single socket configurations. The E5-2600 series supports dual socket configurations, and the upcoming E5-4600 series will support quad socket...

Meaning of Intel (E4) Symbol on CPUs

Does anyone know what the circumscribed e4 symbol after the batch number on the heatsink of Intel CPUs means? It doesn't seem to be something common like the Registered Trademark Symbol (R).

Intel Xeon Question

Even in heavily threaded tasks, I wouldn't bet on the E5-2650 significantly outperforming the E3-1270, if at all. The deficit in clock speed is simply that severe. With an engineering sample of the E5-2650 (clocked at the same 2.00GHz as the 2620, but with 8 cores), I got around 8.35 in...

Will Haswell and Ivy Bridge overclocking properties be similar?

It varies. Conroe clocked significantly worse than Cedar Mill at 65nm, but it also brought substantial IPC improvements on a scale not seen since. At 45nm, the initial C0 revision of Nehalem clocked similarly to the C0/C1 Penryn and Penryn CPUs, but perhaps a little poorer than the E0...

How high will ivy bridge overclock

Hmm, perhaps you're right, I can agree with that. I guess the question is how does Ivy's TDP/Power consumption compare to Sandy's at 4.5GHz+. If it's essentially the same or only marginally reduced, the reduced die size argument does work.

How high will ivy bridge overclock

I've seen this argument repeated a lot, but I'm not sure how valid I think it is. Suppose you clocked a i7 2600K and a i7 3820 at the same speed and same voltage, would the i7 2600K run hotter, when its die size is 216 mm2 vs 294 for the 3820? I haven't seen any tests but I'd be surprised if it...

Ivy Bridge 3570K Testing, Opinions, Results, New Bios, 4.5Ghz At 1.236v

That's possible, but his sample does appear to be a real production version of the chip. A few E1 engineering samples of the 3770K have been tested at the Coolaler forums, and their unlocked multipliers seem to work. I believe there was an E0 3570K tested as well, and it's unlocked multiplier...

Ivy Bridge 3570K Testing, Opinions, Results, New Bios, 4.5Ghz At 1.236v

Well that is unfortunate. You've got the first mass production Ivy Bridge sample I've seen in public hands and the multiplier is stuck. :( Did you try the 2103 bios with it?

Z77 boards now available at newegg

Ahaha, it's more a marketing tactic than an error. NCIX sells the P8Z68-M Pro for 126.99. The 134.99 price point for the P8Z77-M Pro consequently makes a lot of sense. It was never intended to be a $175 product, they just write that to make you think that you are getting a good deal. (I say it...

Z77 boards now available at newegg

Tom's Hardware does mention that Z77 is on a smaller process than Z68's 65nm, but they don't specify which one. I'm going to agree with Concillian that it's probably on 45nm. It seems like they tend to produce chipsets on processes that are no longer used for manufacturing anything else. I...

GTX 680 Release Date?

Do you mean metal layer respin? That would be less complicated than a full base layer respin. Metal layer respin = A0 -> A1 Base layer respin = A0 -> B0

AnandTech Ivy Bridge Performance Preview

On that note it's interesting that Ivy has already been through nine respins and is at the E1 stepping. After all this time and work I wonder if Intel would bother doing another stepping after launch. For comparison Wolfdale launched after 6 respins at C0, and Gulftown launched after just two...
