Make sure before playing games only is setting up your monitors contrast & brightness levels a very important thing to do. I realized recently that a lot of you guys have setup your monitors improperly. How do we know this? Because we receive a couple of email every now and then telling that a reader can't distinguish the benchmark charts (colors) in our reviews. We realized, if that happens, your monitor is not properly setup.
This simple test pattern is evenly spaced from 0 to 255 brightness levels, with no profile embedded. If your monitor is correctly set up, you should be able to distinguish each step, and each step should be roughly visually distinct from its neighbors by the same amount. As well, the dark-end step differences should be about the same as the light-end step differences. Finally, the first step should be completely black.
Tackling the Hyper-Threading myth
The first question that popped into my mind, will Hyper Threading make an actual difference this time around. Surely in the Pentium 4 era quite honestly nobody really cared. But back then the potential definitely was there.
Now when you purchase a Core i7 CPU your mainboard will be configured with HT enabled. Before we begin the entire benchmark session, I just quickly wanted to have a peek IF HT actually makes a difference this time. And oh boy, it surely does ...
So here you see two benchmarks showing two different CPU states. The first being Hyper Threading disabled at BIOS level, the second has HT enabled.
Now as you can see there's a 2500 MB/sec increase with HT enabled in ZLIB. When we look at floating point math a good 2000 ops/s difference in favor for hyper-threading. This is surely looking good already. BTW notice that throughout our review session we have the processor in an overclocked state (stock cooler) at 3600 MHz as well, just to prove how stable this thing is. But let's peek at two more.
Let me fire up the CPU limited 3DMark06, it has two pretty intense CPU tests. Again we see an increase in performance with HT enabled. When we fire up Kribibench and have the processors render 3D imagery we again see a massive win once the mainboard ecosystem has HT enabled. So the generic consensus, definitely leave HT enabled at BIOS level folks. With Core i7 it makes a hell of a difference.
Alright, let's get started with the actual benchmark session where we'll compare performance with a decent set of other competing quad-core processors. We will leave HT enabled throughout the testing session as there just is no reason for disabling it whatsoever, not even gaming.
Intel Core i7 980X review 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 ?
