Intel Core i7 roundup

November 5, 2008 Leave a comment

intel_core_i7Intel has a new processor family on the horizon, and it’s looking like a big performance jump over the current Core 2 range. Integrating new features such as an integrated memory controller, monolithic design and turbo mode. There are many articles already published on the performance of the new silicon, so here is a brief list of where to find the details.

Engadget has a summary of articles

Techradar have gone mad on the i7, with features on game performance, benchmarks, real world tests and even an ultimate guide to the i7

Bit-tech have a very in depth benchmarking review

The general opinion seems to be that the i7 offers a big step up in multi-threaded performance and an improvement for single threaded apps. Looks like AMD is going to have to try even garder to keep up.

Intel’s Larrabee and the future of GPU’s

August 4, 2008 Leave a comment

Just when the GPU war looks like continuing indefinitely as a two horse race, Intel comes along to stir up the market. It’s Larrabee processor is due in 2009/10, and if initial speculation is anything to go by this could change the way GPU’s are used. There’s already been much talk about the use of the parallel processing power of current GPU’s for non-graphical tasks. Physics simulation is an emerging role, and Apple’s next OS, Snow Leopard, will include the ability to easily harness all that GPU power for programmers.

Larrabee is different to GPU’s currently available due to its use of multiple Pentium cores. They’re much improved over the original pentium cores, running a lot faster and incorporating newer technologies. The difference between Larrabee cores and a CPU like the Core 2 Duo is complexity. Larrabee is a simpler design that occupies a much smaller space, making a large number of cores in as small package possible.

Just how much the Larrabee chip can do is still a little fuzzy, and some sites are suggesting it will run applications as well as perform GPU and large number crunching duties. Does this mean current systems using a Core 2 Duo/Quad and Graphics card will be replaced by a Larrabee processor? From Dailytech.com,

Larry Seiler from Intel says, “What the graphics and general data parallel application market needs is an architecture that provides the full programming abilities of a CPU, the full capabilities of a CPU together with the parallelism that is inherent in graphics processors. Larrabee provides [that] and it’s a practical solution to the limitations of current graphics processors.”

If Larrabee performs as well as suggested this could be the biggest shake-up in system architecture for a long time. Convincing users that putting all your processing into one package is a good idea would be another matter.

Hackintosh part 8

February 20, 2008 6 comments

In previous articles I’ve covered the choice of components, build and testing of my new DIY Mac. There’s been very little in the way of problems so far, and I have a machine that measures up pretty well to the current low end Mac Pro. To get some idea of how the hackintosh and Mac Pro compare, here’s a list of components and prices. Read more…

Hackintosh Part 1

February 5, 2008 10 comments

It doesn’t look like the mac 10.5.2 update is landing anytime soon (i’m hoping that saying that triggers a quick release), with macrumors reporting that a new 9C30 seed was released to developers on Monday.

GA-P35C-DS3RRather than sit around waiting I have started planning my hardware purchase. First on the list is a motherboard, and the model I have settled on is the Gigabyte GA-P35C-DS3R. The whole GA-P35 family looks to be fairly popular with the hackintosh community, and most models are listed on the 10.5.1 hardware compatibility list here. The GA-P35C-DS3R supports the latest Intel 45nm processors, DDR2/DDR3 memory, 8 Sata ports and only needs a patch for the built in audio. I’m quite keen to use a Gigabyte motherboard with the Dual Bios feature, having used them for many of my computers. I only once killed a motherboard with a Bios update back in the days of floppy disk updates, and that was one time too many. Everything on this motherboard apart from the built in audio appears to work with no modification. The board is available for £72.56 from Aria, though I will of course shop around before ordering.
