Intel has posted versions 15.22.54.2622 (32-bit) and 15.22.54.64.2622 (64-bit) of its drivers for the Intel HD-series lineup of integrated graphics processors, which includes both Sandy Bridge and older Nehalem-based chips in both desktop and laptop computers. The drivers are available for all editions of Windows Vista and Windows 7.
Of the Big Three players in the graphics market, Intel is the most erratic about its driver releases – their last generic driver was posted way back in September, and while that driver brought a good number of performance improvements and bug fixes, Intel's latest and greatest fixes just three documented issues: a crashing issue with a program called Interstage Studio Standard J-edition, an issue where the driver would change the refresh rate while on battery power, and an issue where content would appear strangely when rewound. Not terribly exciting, given the wait, but I'm sure that the people experiencing those problems are grateful for the fixes.
As always, Intel notes that these are generic drivers which may or may not be missing features present in the drivers provided by OEMs. I've never had issues using generic Intel drivers on any of my machines, from homemade desktops to OEM laptops to Macs running Windows, but your mileage may vary.

If you are a normal desktop user or even a power user with plans to run at over 4GHz, the vanilla LGA-1155 Sandy Bridge platform is good enough. You get some of the fastest CPUs on the market today paired with reasonably priced motherboards and the ability to use Quick Sync to transcode video…er…quickly. If that's not enough, Intel launched a higher end platform last month: the LGA-2011 Sandy Bridge E.
Take a regular Sandy Bridge, add PCIe 3.0 support, increase the number of PCIe lanes that branch off of the CPU (from 16 to 40 lanes), double the number of memory channels (4 x 64-bit DDR3 memory controllers) and you've got Sandy Bridge E and its LGA-2011/X79 platform. SNB-E is currently available in two forms: a 9 6-core Extreme Edition part (Core i7 3960X) and a 5 6-core unlocked version (Core i7 3930K). Neither is exactly cheap but if you need the PCIe lanes, core count and memory bandwidth, they are your only ticket.

Sandy Bridge E is a fairly niche platform to begin with, but what about the niche within the niche (extremeception?) of users who just need the LGA-2011 platform but not necessarily a 6-core behemoth? For those users, there's the Core i7 3820.
Read on for our review!
At the launch of Intel's LGA-2011 based Sandy Bridge E CPU we finally had a platform capable of supporting PCI Express 3.0, but we lacked GPUs to test it with. That all changed this past week as we worked on our review of the Radeon HD 7970, the world's first 28nm GPU with support for PCIe 3.0.
The move to PCIe 3.0 increases per-lane bandwidth from 500MB/s to 1GB/s. For a x16 slot that means doubling bandwidth from 8GB/s under PCIe 2.1 to 16GB/s with PCIe 3.0. As we've seen in earlier reviews and our own internal tests, there's hardly any difference between PCIe 2.1 x8 and x16 for modern day GPUs. The extra bandwidth of PCIe 3.0 wasn't expected to make any tangible difference in gaming performance and in our 7970 tests, it didn't.
Why implement PCIe 3.0 at all then? For GPU compute. Improving bandwidth and latency between the CPU and the GPU are both key to building a high performance heterogenous computing solution. While good GPU compute benchmarks on the desktop are still hard to come by, we did find one that showed a real improvement from PCIe 3.0 support on the 7970: AMD's AES Encrypt/Decrypt sample application.
Simply enabling PCIe 3.0 on our EVGA X79 SLI motherboard (EVGA provided us with a BIOS that allowed us to toggle PCIe 3.0 mode on/off) resulted in a 9% increase in performance on the Radeon HD 7970. This tells us two things: 1) You can indeed get PCIe 3.0 working on SNB-E/X79, at least with a Radeon HD 7970, and 2) PCIe 3.0 will likely be useful for GPU compute applications, although not so much for gaming anytime soon.
This morning Intel launched its all-singing, all-number crunching Sandy Bridge E processors and brand-spanking new X79 motherboard chipset.
It’s not messing around; these are the fastest desktop CPUs that have ever passed across our test benches.
The flagship CPU, the Intel Core i7 3960X, is right up there at the very top-end of processors, and all six-cores of its updated Sandy Bridge E architecture can be yours for nigh-on £750.
So it’s no value proposition then.
There is not a little controversy surrounding it though as despite being sold as a straight six-core CPU the literature Intel has given reviewers clearly shows two dormant or dead CPU cores unused on the die.
We’ve gone into more depth about this in our full Intel Core i7 3960X review.
Still, it is a lightening-fast processor capable of the sort of raw computational prowess you wont see outside of the server environment. It’s also no slouch in the overclocking department either, our review chip managed 4.8GHz in Asus’s Sabertooth X79 motherboard.
It’s not just the top chip that is an overclocking beast, and to demonstrate that we’ve been gleefully playing with YOYOTech’s XDNA Platinum PC.
That’s running the cheaper, mid-range Intel Core i7 3930K Sandy Bridge E running at 4.4GHz out of the box.
The other stand out feature of the new Sandy Bridge E processors and X79 chipset is the support for the next generation of memory; quad-channel DDR3.
Quite what improvements this gives, in real-world terms, over triple-channel DDR3 is rather intangible, and to be honest more indicative of the platform’s server roots than any importance on the desktop.
If you want the full low-down on Intel’s latest offerings, then look no further.
Check out our Sandy Bridge E reviews:
If you want the fastest processor on the planet, look no further. Most impressive is the additional overclocking headroom Intel has delivered over the old six-core chip. Platform upgrades including more PCI-E lanes and SATA 6Gbps are welcome, too.
Asus’s RoG boards are all very well if money’s no object. Back in the real world, the Sabertooth series offers a much more realistic compromise between performance, features and price. The chipset cooling and overclocking support look very solid. We certainly squeezed some great numbers out of the new Core i7-3960X.
With the XDNA Platinum sat on your desktop, purring away quietly as it does, with its cold-cathode tubes illuminating the clean lines of the immaculate interior, even £2,500 worth of buyer’s remorse will have a hard job up against such an impressive machine.

Intel has announced via several Product Change Notifications that it will be discontinuing a total of 19 Clarkdale, Lynnfield, and Sandy Bridge desktop CPUs across sockets 1366, 1156, and 1155. OEMs may no longer order the chips from Intel after December 7, 2012, and boxed CPUs will only be available while supplies last.
The complete list includes the Pentium G6950, G6960, G620, G620T, and G840; the Core i3 540 and 2100T; the Core i5 650, 660, 670, 680, and 2300; and the Core i7 860, 870, 930, 950, 960, 980, and 990X. Many of these processors have been around for over two years now, and with Sandy Bridge and Sandy Bridge E products available at almost all conceivable price points (and with Ivy Bridge just around the corner), the discontinuation of these processors is unsurprising.
More surprising is the cutting of several Sandy Bridge Pentium models, which were released only a few months ago. However, the models in question have already been replaced by slightly faster models (the G630, G630T, and G860, with the G850 apparently still available), and high competition in this market segment from both Intel's own Sandy Bridge Celerons and AMD's offerings is bound to lead to faster turnover.
