Re: INTEL/AMD NEWS Channel

I know it's kinda offtopic question but I want know if intel using the same HSF for e5xxx, e7xxx, e8xxx series ?

Re: INTEL/AMD NEWS Channel

what does that mean, hsf??

Re: INTEL/AMD NEWS Channel

heat sink fan

Re: INTEL/AMD NEWS Channel

Oh, well, maybe, cuz they are all the same processors. The only physical difference is the cahce size(and 10 million transistors less on E8xxx than the other C2D).

Re: INTEL/AMD NEWS Channel

I think E8xxx still gets the old P4 like HSF, while E5xxx and all comes with the new HSF which is thin and looks like Hyper LE...the old one is more efficient IMO.

Re: INTEL/AMD NEWS Channel

Yeah I wanted to know about the heat sink fan. Thanks MetalheadGautham for explaining this to comp@ddict.

@ comp@ddict - I know that @ the core they are all same procs ( or I should say almost ) but only differs in multiplier, bus speed & cache size - thanks for reinforming

@ j1n M@tt - thanks buddy for confirming that. I saw intel e5xxx & e2xxx series hsf & they were same. So I was just curious to know that if all 45nm intel procs ( apart from core ix ) have the same hsf

Hi, how come this AM3 mobo be only 84$ [4k in math].
*www.newegg.com/Product/Product.aspx?Item=N82E16813128392&Tpk=MA770T

DDR3, ultra durable 3 caps, extreme OC, full ATX mobo, supports PII. If it comes here, it shud sell at 5~6k rite?

and new AII and PII is almost here, with pII 550 @ 105$. OC to 4GHZ on air.

Re: INTEL/AMD NEWS Channel

And here is the pic of both HSF. *www.watch.impress.co.jp/akiba/hotline/20080119/image/kc2d6.jpg

btw, older p4s used slightly bigger n heavier hsf than both these.

AMD Phenom II X3 720 BE(7700/-) compared with Intel Core i7-920 Processor BX80601920(15000/-)

I think there's a psychological obsession that most enthusiast consumers have with certain products. I won't get the social defect of admiring the most expensive product and considering it 'the best'. Sometimes, defining that term 'best' is not as easy as pointing at numbers on a benchmark. Take for example cell phone; the most expensive model is not necessarily the best performing, and it might be overpriced because of other features that inflate the products demand. Sometimes I think that gamers make this mistake, as I often see poor advice given to first-time system builders to spend as much as possible on the processor. Why?


For many, performance may be defined as a artificial score from a synthetic benchmark. But when it comes down to it, the person who can play games, browse the Web, rip music, and update their personal finances at the same speed with one processor as they could another, I begin to become wary of how we calculate performance. If the Core i7-920 could render a better frame rate, or open my programs faster, I might easily declare the AMD Phenom II X3 720 BE a subordinate CPU. Since only a few benchmarks could place the Intel processor ahead of the AMD counterparts, it seems that we must rely on other factors to define performance... such as functionality, overclock ability, and value.

don't compare the prices in newegg, if u look in the product details page, they will say its without box shipping which costs less...so no accessories.

If u compare that way intel CPUs and their mobos are more cheaper in newegg...Asus P5Q Deluxe is for 4.5k+shipping in newegg, which is around 13k here!!

Synthetic scores and benchmark charts for games, etc are great actually. But I would advice everybody who looks at two CPU's scores to divide each of the scores by their cost. This would give you the REAL value of the product you buy.

As a rule of the thumb, always try to get the maximum VFM out of your builds, after you compare CPUs which will be future proof for your purpose.

Unlocking AMD CPU Cores Safe Say Mobo Makers

While browsing through motherboards at Computex, several manufacturers were quick to tell us some details about the recently released dual-core Phenom II CPUs from AMD.

Two motherboard makers told us at the show that AMD's new processors are safe when unlocking disabled cores. In fact, one motherboard maker even told us that when you unlock the disabled cores, they run at slower frequencies than the normal cores.

This is of course all incorrect, and it is indeed not a safe guarantee when you unlock the disabled cores. The reason for this is that the disabled cores are turned off for a reason: they failed factory tests. Cores can fail for any number of reasons, including defects in the silicon, problems running at full frequency, or a bug introduced during manufacturing.

Both AMD and Intel disable CPU cores for this very reason.

When you unlock the disabled cores, they will run at full processor frequency, since you cannot run each core at different speeds. While you may see initial gains and benefits from turning a dual-core CPU into a quad-core CPU, you may introduce instability into your system. Things may corrupt, calculate incorrectly or even crash.

Despite what we were told, we still recommend that if you're going to unlock disabled cores, do so with caution in mind--there is always a risk that something will go wrong.

^^Nice one. Comp@ddict, can you maintain an index of these news articles posts in the first post ?

I think cores are also locked because of inability to overclock properly. Thats the reason P2 550 BE Unlockers found that the 4-core version OCs much worse than the 2-core version.

And the indivudual cores are clocked at the same frequency even when saving power due to a REASON.

Here is a quote from a review of AMD Athlon II X2 250.

All of our benchmarks were run with power-saving features enabled. AMD actually weighed in just after the entire suite had been completed to recommend against testing this way because, currently, the two cores on its Athlon II X2 are changing P-states independently. An upcoming BIOS code update will have both cores shifting P-states together. The problem with independent switching, according to AMD, is that single-threaded workloads with a tendency to hop from one core to the other will experience a slow-down due to operating system scheduling inefficiencies.

This phenomenon is best-illustrated with an example. If you have two cores and are running a Lame .mp3 encode, then one thread is idle (since the encoder is only single-threaded). Scaling that idle core back to 800 MHz while the utilized core does its work at 3 GHz helps cut back on power, reduce heat, and so on. But if Vista’s scheduler bounced Lame over to the idle core running at 800 MHz, you’d incur a significant performance impact all of the sudden. While it is common to see a single thread of Prime95 bouncing all over the place, I kept an eye on Lame and WinZip and am fairly positive these apps weren’t getting affected by this potential issue.

AMD’s implementation is the “right” way to go about optimizing for efficiency, but it’s hampered by Microsoft. Phenom II “fixed” this behavior by keeping all cores running at the same speed. If I understand AMD correctly, the upcoming BIOS will shift from Phenom- to Phenom II-like operation. With all of that said, testing with Cool’n’Quiet enabled works to AMD’s benefit when it comes time to measure power, since all of these CPUs are able to throttle down to 800 MHz while they idle.

AMD Athlon II X2 / Phenom II X2 And Low-Power CPU Bonanza

Source: *www.tomshardware.com/reviews/phenom-ii-x2,2324.html

When it rains, it pours, right? Computex is now in full swing, and every company with something substantial to announce is going to do it in Taipei, in front of as many people as possible. AMD just so happens to have a lot to talk about this year.
The company is launching four different desktop processors (in addition to its server news). They’re all fairly well focused on areas where AMD has excelled lately: value-based performance and low-power.
Two CPUs are 65 W versions of hardware AMD is already shipping. The Phenom II X3 705e and Phenom II X4 905e both run at 2.5 GHz and offer substantial power savings versus the other 95 W X3s and 125 W X4s currently available. We dropped these into our Maui-based HTPC for a little high-performance home theater action.
*media.bestofmicro.com/athlon-ii-x2,D-I-213030-13.jpg*m.bestofmedia.com/i/presencepc/design/loupe.gifZoom
The third new CPU is an inevitable adaptation of AMD’s quad-core Deneb design, which has already lost one execution core to become Heka, and now loses a second core to become Callisto. Fittingly, the resulting product is referred to as Phenom II X2.
Fourth on the menu is a new architecture that begins its life as a native dual-core processor. Dubbed Athlon II X2 (internally named Regor), this one boasts a larger L2 (1 MB per core), but gives up the L3 entirely. We’ll look at how this affects performance in our benchmarks, of course

Keep reading for an amazing review of AMD's new offerings.

The funny thing is that as obvious, while the Core2 architecture beats Phenom2 clock to clock on all tasks, here we see that IN GAMING EXCLUSIVELY, a Phenom2 X4 905e @ 2.5GHz BEATS a Core2Quad Q8400.

 

[comp@ddict]

Whoa, and anandtech did a review where they concluded Q8300 is faster than X4 955 lolz

 

[MetalheadGautham]

^^ROFL. AnandTech and TomsHardware are both getting Pro-Intel and Anti-AMD these days. Excessively so. Yeah the review I told about was by toms but in general, fact remains that both TH and AT bash AMD more than needed.

Ha! But is it reliable?

 

[j1n M@tt]

ya it's true...Intel discontinued i7 920 and 940, and dats old story now.

 

[MetalheadGautham]

Yup the discontinuation is an old story.

But Intel Promised that the i7 920 will be retained for a little more time, but in the end, i7 CPUs 920, 950 (940 gone already) and 965 will go.

The LGA-1336 will be a rich exclusive platform and also a co-platform for servers (there is also the LGA-15xx something for HIGHER THAN HIGH end servers).

Cheaper motherboards on x58 chipset will be phased out, and by the time Westmare becomes mainstream around 2011, this platform will be reserved for high end CPUs, in a way similar to AMD's FX Line.
