P4 3.0

I och med att Prescott presterar sämre än Northwood i allt de kunde mäta - nej.

En AMD Athlon64 3000+ med ett bra moderkort och ett Radeon 9800. Vilket Radeon är upp till din plånbok. Vill du hellre ha nVidia, ta ett FX5900, de kostar inte mycket mer men presterar så mycket bättre.

"If you’re looking for nothing more than a purchasing decision let’s put it simply: if you’re not an overclocker, do not buy any Prescott where there is an equivalently clocked Northwood available. This means that the 2.80E, 3.00E, 3.20E are all off-limits, you will end up with a CPU that is no faster than a Northwood and in most cases slower. If you are buying a Pentium 4 today, take advantage of the fact that vendors will want to get rid of their Northwood based parts and grab one of them. "

"Just as was the case with the very first Pentium 4s, Prescott needs higher clock speeds to spread its wings - our data on the previous page begins to confirm this. To put it bluntly: Prescott becomes interesting after 3.6GHz; in other words, after it has completely left Northwood’s clock speeds behind."

"Although there are a lot of innovations introduced in the Prescott core, which should theoretically increase the performance of the new CPU, such as larger L1 data cache and L2 cache, the processors on this core are very unlikely to make a significant breakthrough in processor performance compared with the previous processors on NetBurst architecture. The thing is that they provided Prescott with a 1.5 times longer execution pipeline in order to increase the clock frequency potential. That is why all the innovations improving the processor performance now serve to make up for the negative influence of the longer execution pipeline. Besides, the increased cache-memory size caused a significant growth of the latencies of both caches, which can also slow down the processor in certain tasks."

"In conclusion I would only like to add that the greatest consumer drawback of the new Prescott core, which has nothing to do with its architecture, is a significantly higher heat dissipation compared with the previous solutions. It will push the mainboard makers to developing new platforms for this CPU and new cooling solutions for Prescott based processors faster than 3.4GHz."

"In our opinion, the debut of a processor based on a cutting-edge process technology and architecture that only offers the same performance level as the predecessor is unanticipated. Despite 1 MB L2 cache and some optimizations, Prescott is slower than Northwood in roughly a third of our benchmarks. Software, like many 3D shooters and more serious applications like Lame, MS Movie Maker 2, Mathematica, Cinema 4D or even 3DStudio perform worse than before."

"We should as well put the considerable heat dissipation onto the list, as the Prescott offers no improvement in this increasingly important category. Users willing to upgrade their socket 478 systems are left out in the rain due to the uncertain compatibility situation and last but not least Prescott is badly overclockable, which made us skipping the overclocking tests. So there is only one argument left that makes Prescott really attractive: It is a new technology and it is not more expensive than Northwood. "

"What we do not understand is why Intel presents a new technology, flavored with lots of marketing-friendly numbers, only few months in advance of a platform change. So what is the meaning of this "average Prescott" we were given today? The introduction of SSE3 cannot possibly be that important. We only found one benchmark supporting the new instructions, and it does not even benefit from it. At existing clock speeds, Prescott is not faster than Northwood and is thus a pretty useless product, as the socket is meant to be phased out shortly anyway. "

"As you can tell the Prescott is pretty hot! Also keep in mind that our testing was completed on an open test bench with the board laying flat. If you're case has poor ventilation and you are thinking of picking up a prescott you might want to invest in a better cooling case and heat sink for the processor. To be blunt, and to the point, forget about overclocking or even running the Prescott in an un-air conditioned room with the heat sink that comes with the boxed retail version (unless Intel Improves it). Even though the chart shows the retail HSF at 70C we stopped testing at this point and the temperatures were still rising. "
