AMD Phenom X3 8750 Tri-Core Review & Overclocking Analysis - PAGE 1
William Henning - Like +my favouritesToday AMD is releasing the Phenom Tri-Core processor, and they were kind enough to send us a Phenom 8750 for testing.
The AMD Phenom 8750 runs at 2.4GHz (12x200) and is based on the same die as the quad core Phenom processors. As you may be aware, the initial launch of the quad core Phenom processors was plagued by the "TLB erratum" - a bug that could cause occasionally cause the processor to hang under certain heavy loads. Since then, AMD has come out with a new 'B3' stepping of the Phenom die, and this stepping apparently fixes the erratum - which is a very good thing as in our testing, the microcode based fix could have a significant impact on performance.
As we have covered the initial Phenom 9600, and the yet unreleased Phenom 9900, we will not cover the Phenom micro-architecture here; as there have been no changes since that time - other than the TLB fix.
So what is a Tri-Core processor?

Simple.
It is either a quad core processor where one of the four cores failed AMD's quality control testing, and had the defective core disabled - and is now sold as a tri-core - or it is a quad core processor that had one of its working cores disabled in order to be able to market a tri-core SKU.
Regardless of how it became a tri-core part, I was interested to see how our 8750 would perform compared to not only the quad core Phenoms, but also a "Black Edition" dual core AMD 5000+ X2. I also threw in a comparison to a Core 2 Duo E6750, a 2.67GHz part - giving it a 267MHz speed advantage at stock speeds - to see how the tri-core would compare to an equivalently priced dual core Intel part. After all, AMD is trying to position the tri-core parts as a viable alternative to some dual core parts -- so let's see if they accomplished this goal with some testing.

Or spend $45 more and don't bother re-engineering for months, with great frustration. Besides, AMD is throwing out what they consider a new chip that's less in production cost for themselves but only at a discount of $40-50 USD of the real thing X4. Why does AMD bother with, "well, we don't have anything like what you want, but we've got this thing we've been kicking around..we were going to throw these away but found out they still work" ??? makes them look weak and defeated.
Don't get me wrong, I'm an AMD fan, but I think the company is running a 1-legged race against themselves...not Intel with these CPU's. A 5000+ Black Edition is currently available in the USA for $87.00 USD shipped...the X3 is Minimum $148.00 shipped and the differences between the X3 8450/8650/8750 are a nill...200Mhz difference from bottom to top performer. Same cache, same stats... differences are only 2.1/2.3/2.4...with pricing at $148.00/$165.00/$195.00. Would any of you go out and buy a new motherboard and one of these when you can perform on equal ground with its predecessor by overclocking an $87.00 CPU on your existing AM2 board?
It's a little silly. And AMD is getting more and more silly daily. Not an Intel fan, but when they're boasting an upcoming 6 and 8 core CPU coming later this year...and AMD is boasting a 3 core and 4 core CPU that they finally fixed after releasing thousands of fundamentally broken ones...It's embarrassing to brag about any AMD allegiance with other members of the gaming or computing community.
What it is: A Phenom X3 Cpu is a Phenom X4 that had one defective core, AMD Disables this core and its cache and sells it as a tri-core cpu, saves them/makes them money and gets better yields that way. say 80% of quad cores turn out good, and another 12% turn out with one faulty core, it gives them 92% yield over 80% Yield. its quite a good move, especially since Intel CANNOT do this as their quads are just 2 fused C2D's AMD uses 4 independent cores thus making them alot more versatile.
On Paper AMD Should be the king, they just can't pull off the workload per-clock that Intel is right now, its only a matter of time until they make a come back and take the crown imo. especially since Intel seems do be already going back to their MHz/FSB Quad pumping dependncy taht we saw in the 3.6ghz P4's that were getting wrecked by 2.2ghz AMD's.
Few prices:
AMD Phenom X3 8650 Triple Core Processor Socket AM2+ 2.3GHZ 3.5MB Cache 95W - $169.99 CDN
AMD Phenom X3 8750 Triple Core Processor Socket AM2+ 2.4GHZ 3.5MB Cache 95W - $199.99 CDN
The prices are decent but I think to be competetive they have to slash the price a bit more than that already see'ing as the X4 2.4GHz is only $45 more, which is barely a premium and for $49 more you can get a X4 9850 Black edition.
I would expect a tri-core processor to beat a core 2 duo, but how much improvement do you think the Q6600 would be over the tri-core?
