Intel Core i7 920 and 965 review -
5 - Hyper Threading, X58 and Socket LGA 1366
Inevitably chips based on the Nehalem family will have between two and eight cores, and will be capable of handling two independent software threads per core. This is called Hyperthreading, Intel's name for the concept. It allows a processor to execute two different code streams at pretty much the same time.
This was a feature found in Intel's single-core Pentium 4 processors but largely discontinued with the advent of multicore chips, but it's essentially the same technology as before. With two threads per core, Core i7 chips will pack no less than eight logical cores at launch. If you look at the screenshot to the right you can see that happening. We'll do some benchmarks today with both HT en- and disabled, you'll be surprized how much difference it made.
The X58 Chipset
The Intel Core i7 processors will be paired with the Tylersburg chipset, you guys know it as the Intel X58 Express chipset. This new chipset will use the same ICH10 "south bridge" as the new Intel P45 (Eaglelake) chipsets, but the X58 chipset will obviously overall be radically different:
- The X58 Express will use the new LGA1366 socket (also known as Socket B).
- No more memory controller
- Intel QuickPath Interconnect (QPI) the interconnect between the Core i7 processor and the X58 Express.
Some other major features are obviously the discussed support for two x16 PCI Express 2.0 slots with the option for four x8 slots to support quad-graphics cards (CrossFire X) and if certified by NVIDIA SLI. We'll deal with X58 in a separate articles though.
Socket LGA 1366
We just talked you through the new complexity of the architecture, yet also future scalability. In order for Intel to keep pushing where it needs to go, it needed more wires and pins. Unfortunately that means that you can't upgrade existing Intel Core based PCs with Core i7 chips as socket LGA 775 is now replaced with socket LGA 1366.
There is however a horrible rumor that yet another LAG socket will surface later in 2009, socket, LGA 1160 for mainstream processors with an expected arrival in 2009. That's a bit tricky, and hopefully Intel will stick to just one new Socket, Socket 1366.
Intel reference X58 motherboard
We test the Gulftown based Core i7 980X. Intel launches the Core i7 980X processor today priced at US$ 999 in thousand-unit tray quantities. It's scrumptious, it's delicious. Really it overclocks brilliantly as well; it's dark demonic matter my man. Head on over to the next page where we'll start up a technical overview and then head onwards to an extensive benchmark session, and sure... we'll throw in an overclocking session as well. We've got a lot of ground to cover.
Alphacool HF 38 Niagara Intel Core i7 CPU water block review
There aren't that many companies out there that offer liquid cooling products which you can purchase separately. There's a handful of them. One of them is the German based Alphacool. Recently they introduced a new CPU block called the Alphacool HF 38 Niagara. This new water-block is designed for Socket 1366 processor, aka Nehalem aka Core i7. A high-end liquid cooling CPU block priced fairly. Let's check it out.
Intel Core i7 920 and 965 review
So today Intel launches these Nehalem based puppies on the new name Core i7 as in their 7th architectural generation. A name that will catch on quickly and you'll get used to just as quick as well. No less then three processors are announced today and Guru3D.com will taken a look at two of them.
Intel Core 2 Extreme QX9650 processor review
See, a Core 2 Extreme X6800 is pretty much the fastest desktop processor in the world, yet adding two more cores gives you the absolute best of both worlds. Get the highest stock clock speed Intel offers for the best performance in lightly multithreaded (or single threaded) applications, and a total of four cores for those heavy multitasking or CPU intensive multithreaded scenarios. Really, you can't lose there now can you ?
