AMD has just rolled out a whole new bunch of Phenom II and Athlon II series processors working at increased clock rates. We are going to check out the most interesting offers and see if AMD products are still attractive in users’ eyes.
Intel decided to disturb the calm summer days by slightly raising the clock frequencies of their LGA1156 processors. The most interesting product among the newcomers is Core i5-760 - a quad-core processor that on the one hand - belongs to the "elite" Lynnfield family, but on the other - boasts a pretty democratic price tag.
A few weeks ago we previewed the performance of Intel’s next-generation microprocessor architecture, codenamed Sandy Bridge. We came away impressed with our early look at performance but honestly had very little explanation for why the chip performed the way it did. For the first time in years we knew the performance of an Intel processor without knowing much about its underlying architecture.
Today, that all changes.
Sandy Bridge is Intel’s 2011 performance mainstream architecture refresh. It won’t take the place of the 6-core Gulftown based Core i7 processors at the top of the charts, but it’ll occupy the competitive space below it. The value segments won’t see Sandy Bridge until 2012.
The first CPUs will ship very early in 2011 for both desktops and notebooks. The architecture discussion we have here today applies to both. The CPUs won’t be called Sandy Bridge but instead will be called Intel’s 2nd generation Core i3/i5/i7 microrpocessors.
The CPUs will require a new socket (LGA-1155) and all new motherboards based on Intel’s forthcoming 6-series chipsets.
The chipset brings 6Gbps SATA support (2 ports) but no native USB 3, motherboard manufacturers will still have to use an off-chip controller to get USB 3 support. Intel will also enable 5GT/s PCIe 2.0 slots with its 6-series chipsets.
I ran into an old friend of mine who happens to work for Intel at an industry event last month. We were naturally talking about Intel when he pointed out that the company was doing very well. I agreed, but argued that Intel’s progress was being artificially limited by the fact that it wasn’t facing much competition at the high end.
It’s true. AMD’s entire desktop product line exists below $300, and we won’t see a real push for the high end crown until next year with Bulldozer. Until then, the real competition happens at lower (and arguably more interesting) price points where AMD gives you more cores for less, while Intel offers lower power consumption and better single threaded performance.
The ultra high end is still alive and well, despite the lack of competition in the market. Apple just announced its own dual-socket, 12-core monster that will begin shipping next month. Even Intel will tell you that it’s seeing more interest in the Core i7 980X than any previous Extreme Edition part. And the interest isn’t misplaced.
s the first 6-core desktop CPU based on Intel’s 32nm Gulftown core, the Core i7 980X was the first Extreme Edition in years to offer more than just a clock speed advantage. You got more cores, a larger L3 cache and virtually the highest clock speeds Intel has to offer. If you run highly threaded workloads, you can’t do any better on the desktop today. Thanks to its turbo modes, you don’t even give up performance in lightly threaded apps either.
The 980X of course carried an extreme price tag at $999. With more competition at the high end we might’ve seen derivative parts offered at lower clock speeds and lower price points. But until AMD delivers Bulldozer the impetus just isn’t there. Instead what we’re left with is a slow moving waterfall.
Early next year (Q1) Intel will introduce the Core i7 990X, a clock bumped version of the 980X. Presumably the 990X will run at 3.46GHz by default, but have the ability to turbo up even higher. The roadmap calls for another clock bump in Q2 depending on what AMD does.
Below the 980X there’s only a single 6-core desktop part for at least the next 6 months: the Core i7 970.
Several months ago, I wrote about my little experiment with Clarkdale, where I built a small form factor system, based around a Core i5 661 CPU, an Asus H55 motherboard and a Radeon HD 5850 graphics card. That system also used a pricey, 250GB SSD, which was a little over the top for an otherwise modest system, but the idea was to make it small, quiet and low power.
Quite a few people critiqued the article, and most of the critiques revolved around the lack of performance data. After all, the general feeling went, how do we know this is really a good system? It’s pricey, to be sure, but we also have no way of judging performance.
As it happens, I have another small form factor system in the basement lab, which happens to be running a Core i5 750. Ignoring hard drive performance for the moment, all I really needed to do was swap out the graphics card, since the Lynnfield system was running an older Radon HD 4870. So I dropped in a Radeon HD 5850 and took both systems for a spin.
AMD followed into Intel’s footsteps and launched their six-core processors as well. However, they used a completely different approach: AMD decided not to switch to new manufacturing process or develop a completely new semiconductor die. However, as a result we got a Phenom II X6 – a mainstream and affordable processor with six computational cores that has no analogues and is compatible with Socket AM3 form-factor.
<p><span style="font-size: small;"> In most of my CPU reviews I tend to focus on light overclocking - the low hanging fruit if you will. Over the past few years the focus has shifted from absolute performance to performance per watt. An overclock stops being so interesting if you have to incur a huge power penalty to get there. That's the reason I've put more emphasis on stock voltage overclocks in the past few years.</span></p>
<p><span style="font-size: small;">The fact that I was able to get my Phenom II X6 1090T running at 3.8GHz with minimal effort was very impressive in my opinion. Remember that unlike Gulftown, AMD didn't get the benefit of a process shrink with the Phenom II X6. Six cores and nearly a billion transistors running at 3.8GHz with less than 10% more core voltage is awesome.</span></p>

A very smart man once told me that absolute performance doesn’t matter, it’s performance at a given price point that makes a product successful. While AMD hasn’t held the absolute performance crown for several years now, that doesn’t mean the company’s products haven’t been successful.
During the days of the original Phenom, AMD started the trend of offering more cores than Intel at a given price point. Intel had the Core 2 Duo, AMD responded with the triple core Phenom X3. As AMD’s products got more competitive, the more-for-less approach didn’t change. Today AMD will sell you three or four cores for the price of two from Intel.
In some situations, this works to AMD’s benefit. The Athlon II X3 and X4 deliver better performance in highly threaded applications than the Intel alternatives. While Intel has better performance per clock, you can’t argue with more cores/threads for applications that can use them.
When Intel announced its first 6-core desktop processor, the Core i7 980X at $999, we knew a cheaper AMD alternative was coming. Today we get that alternative, this is the Phenom II X6 based on AMD’s new Thuban core
It’s still a 45nm chip but thanks to architecture and process tweaks, the new Phenom II X6 still fits in the same power envelope as last year’s Phenom II X4 processors: 125W.
Year 2010 will be remembered in the computer industry as the time when six-core processors entered the desktop segment. Intel was the first one to announce their six-core solution – a 999-dollar Nehalem modification featuring more computational cores and manufactured with 32 nm technological process.
We received Dell's latest R810 server for review, coupled with the Intel Xeon X7560. The R810 supports two or four octal-core Intel Xeon Nehalem EX processors, with the potential of running up to 64 threads and half a Terabyte of memory. It also includes enhanced RAS features and hopes to compete with the RISC heavyweights like IBM's Power 7 servers, only at a much lower cost.
With stiff competition from AMD's Magny-Cours servers, IT professionals need to focus more than ever on the intended use before diving into a new server. We'll show where the Xeon EX does well and where other solutions have an advantage as we look at the R810 and Nehalem EX.
