Processor Intel V8 Eight-Core Platform Preview

X-bit Labs tests what would seemingly be an enthusiast's dream machine. But does this octal-core rig perform as well in the real world as does on paper?

Multi-core paradigm has become one of realities of our life. The users had a chance to enjoy the advantages of CPUs with two computational cores and as a result the sales of these processors keep growing day by day. At the same time, it is absolutely clear that we haven’t yet hit the apogee of the core multiplication process. Quad-core CPUs start pushing their way into the market and at this time they are positioned for higher priced systems for computer enthusiasts. The ever growing interest to platforms optimized for multi-threaded performance inspired CPU manufacturers to introduce high-performance dual-socket computer systems featuring two multi-core processors inside.


AMD Company probed the path in this direction with their Quad FX platform built with two dual-core Athlon 64 FX processors. The launch of this platform was primarily stimulated by AMD’s desire to respond to quad-processor solutions from their competitor, because technological difficulties wouldn’t let AMD release their own solutions featuring four processor dies in a single package at that time. However, our tests revealed that at this time AMD Quad FX platform yields a lot to Intel quad-core processors, such as Core 2 Quad and Core 2 Extreme, from all standpoints, including the performance. Although despite this fact AMD managed to impress its fans with the prospects for future evolution of their Quad FX platform. Company representatives promised that dual-socket desktop platform would continue evolving after the prospective quad-core processors on K10 micro-architecture come out. It means that Quad FX platform will eventually allow building systems with the total of eight processor cores in them.

Of course, Intel couldn’t leave this initiative unattended. The micro-processor giant strengthening its positions day by day after the launch of Core micro-architecture, couldn’t disregard the competitor’s ability to introduce a desktop platform with two quad-core processors in it. The “refreshed” Quad FX platform will be known as FASN8 and will feature Agena FX codenamed CPU. And even though it is scheduled to launch only in Q3, Intel began pushing its alternative solution in January already. The first demonstration of the concept system equipped with two quad-core processors on Core micro-architecture was performed at CES 2007, where it was codenamed V8. These days Intel has already mastered mass production of all components for this platform and of course, we couldn’t help getting our hands on them right away.

will we never see a cpu much above 3ghz?
seems like everyone has hit a wall and is adding more cores and expecting software to catch up.
8 cores is just out of hand and i dont see it as being practical.

I think the problem is not that we hit a gHz wall. The problem is we hit a thermal wall that is not really energy efficient but not cost effective either. Air cooling on a heatsink can cool so much heat before it becomes useless. As you can see with the right type of cooling, any cpu can easily hit alittle over 4.5ghz or higher. But where talking about liquid nitrogen that is not user friendly and extremely expensive for the average joe.


I think the future of standard cpu cooling found in everyday retail eMachines, HPs, Gateways and etc, will be simplified version of heat pipes and water cooling once cpu's again start to climb the gHz ladder once again. And take note that the future of cpu's is not the speed of cpu processor, but how efficient it can handle and process general instructions in multicore setups. I can write an article on how this works. Remember the Athlon XP days, when a 1.8ghz AMD cpu could easily rival an Intel P4 3.4ghz cpu? The future is multicore due to extreme thermal demands of a highspeed 5.0ghz or beyond cpu.

In addition to this, a big factor is also that both AMD and Intel are trying to keep frequencies down while increasing the amount of work done per clock cycle. I remember one article about Barcelona where a 2.3GHz would rival a 2.9 or 3.0GHz from the current generation. Along with this, applications will finally start to be coded with a multi-threaded design at some point, which will provide better performance from dual/quad core processors.
