Source was from Techradar and ZDNet. Occording to them, a Sandy Bridge CPU was overclocked to 4.9 GHZ ON AIR! I can only imagine the performance when water cooling is applied D: They still need to verify the scores on cinebench, but bby the looks of things, we might have a major overclocker on our hands http://www.zdnet.com/blog/computers...pu-to-49ghz-outpaces-12-core-amd-opteron/3863 http://www.techradar.com/news/compu...ndy-bridge-performance-what-s-it-like--716680
That is particularly impressive, especially for the "value add" overclocker, however it still at a significant cost to 'enthusiast' overclocking: From what I've heard so far (it could change) SB is limited to 2,133MHz DDR3, despite the fact 2,500+ is already available and higher performance parts should only get cheaper. It's an issue if you're in the performance memory industry, but we recommend 1,600C9 for LGA1156 and I can't see that changing for LGA1155 that uses even more aggressive pre-fetching. In fact, I'd put money on lower latency being better than frequency. The biggest kicker is that no bus changes mean no uncore overclocking, where a lot of the memory performance is gained. Questions remain on: Budget overclocks of non-K products Price of K-products Quality of RETAIL K-products - are they all going to hit 4.5+? Advantages of Ks: Use of cheaper motherboards because it only depends on the CPU socket and its power provision since the bus' are all staying in normal tolerance.
A good post I am also wondering on the price of the K product range, im expecting them to be quite expensive now. If only they showed a CPU using the X68 chipset being overclocked
Come back in Q2-2011 for X68 and I would be very surprised if prices didn't start at "Xeon" level of several hundred dollars imo. Intel wants to increase the average selling price and push K-series onto enthusiasts, not cheap Skt2011 parts like an i7-920/930. The 4.9GHz was on an "i7-875K" part - it's most expensive/highest rated. No word yet on its lower "i5-750" equivalent.
Without shelling out for the K-series overclockable parts, it seems the clock speeds won't be past what you can achieve with an i5/i7 today (~4GHz). I anticipate that there will be work-per-clock benefits, but it seems to me that if gaming is the priority then there's not going to be much need to upgrade from an overclocked i5/i7 to Sandy Bridge ... we can probably skip straight over to the 22nm Tick (is that Ivy Bridge?) and just focus on new GPUs for a while.
anandtech are pricing the 2600k at $562 (*facepalm*), but the 2500k is apparently $205 based on current pricing http://www.anandtech.com/show/3922/intels-sandy-bridge-architecture-exposed/8 Near the bottom of the link
Hmm I was thinking of switching over to the German team after this Intel build, I guess not. Unless AMD can get more instructions per clock or beat 5ghz overclock because im totally going to watercool it.
