THG Labs In Depth With AMD Spider 103
The Last Gunslinger writes "Tom's Hardware Guide has published detailed results of their laboratory analysis of AMD's recently released Spider platform, including the Phenom 9500 and 9600 running on 790FX chipsets. Amongst other interesting details, the 2.4GHz Phenom 9700 has been pushed back to Q1 2008. The 2.3GHz Phenom 9600 benchmarks on average 13.5% lower than Intel's Q6600 quad-core CPU...and the MSRP for the Phenom is about 13.6% less as well. Much is made of the AMD OverDrive utility, by which the THG labs were able to OC the Spider platform by 25% (3.0GHz) using air cooling alone."
Four graphics cards! (Score:2, Interesting)
With the new 7-series chipset family, consisting of the 790FX, 790X and 770, AMD is simultaneously unveiling the Spider platform. Up to four graphics cards can be set up as a Crossfire X configuration using the new 790FX chipset.
Four graphics cards! Now that sounds like a gamer's wet dream. These days, CPU performance is not nearly as important as GPU performance. Four GPUs, running in parallel, with the right level of support in DirectX and OpenGL and you can just imagine those FPS! That's the real news of interest in this article, IMHO.

It's currently annoying to parallelize the compilation of a single source file, but non-trivail applications have a whole bunch of source files - so parallelizing compilation of applications is really easy.

AMD underwhelms us, again. (Score:4, Interesting)
And almost everyone with a Q6600 can get it up to 3GHz on air too, even on the stock heatsink. With something a little more special, like a Thermalight air cooler, speeds of 3.4->3.6GHz are not uncommon. If we look at the benchmarks in the TomsHardware article, the Phenom gets its ass kicked nearly everywhere across the board. It can be argued that this is because most apps are not optimized to work on quad-core chips yet, but even in the benchmarks where quad-core is clearly a benefit, Intel still edges out a respectable lead with their reasonably older technology.
The advantages of the Spider platform are that you won't need to buy a new board for future processors
We've heard that before! Okay, AMD has done something pretty clever with making the chips compatible across the board.. but I'm willing to wager that the percentage of PC owners who actually upgrade their machines year by year is reasonably low. There are a lot of enthusiasts who do it, and this is likely AMD's market if their performance wasn't so poor compared to Intel nowadays, but computer parts are cheap enough to get a new machine every couple of years instead. Certainly this won't be of any interest to the main manufacturers.
Still, I'm glad AMD's there. Their presence is helping to keep Intel honest and the prices generally low, but as an ex-AMD diehard, I'm not seeing any reason to go back to them yet.

That's because intel's front side bus architecture, off chip memory controller and inefficient caches hinder performance, especially under heavy multitasking. You'll also note that multiprocessor (i.e. multicore) intel systems scale very poorly as the number of cores (or processors) goes up compared with AMD processors which have a more sophisticated design.
As code becomes more parallel as a matter of course, we'll see these effects becoming more important. Next year, intel is bringing out a more AMD-like NUMA architecture (new processors, chipsets and motherboards) to try to address these issues. AMD has a 5 year headstart.

The AMD's are less powerfull then the Intel in this race. Okay, no harm done, but why on earth does AMD then price them at the same dollar for performance ratio as intel? Lets say intel charges 100 bucks for 100 performance points, AMD now says, well we can't give you those same 100 performance points, instead we can only give 80, but aren't we nice, we only charge 80 bucks for it.
Sounds nice in theory, but if I am buying a new cpu at the top of its range (and therefore paying a premium) I want to either have the highest speed OR a far better deal. Computer components often are priced on a curve, the slower, the cheaper, usually leading to a sweet spot where you get the best price for performance. Is it smart of AMD to make straighten this curve into a line? For 13% more power, intel just charges 13% more? No wonder they are losing once again, they used to be the company that was the best value for money. Perhaps they need a reality check AMD YOU ARE NO LONGER EQUAL TO INTEL, the days that your CPU's were better are over so you can't charge as much anymore.
a performance of 80 for a price of 50, now that would be a sweet, I could then reason that, well I get less power, but I save a lot of money. At this rate, I might as well buy an older intel and get a far far better deal.
