More information about Ivy Bridge processors and their performance
Earlier this week we published a list of 18 models of the Intel family of Ivy Bridge, which will be released next year. This line includes models Core i5 and i7 3000, aimed at different market niches. Recently, a network of commercial hit Intel plans for 2012, which confirmed a number of these processors.
Slides show that Ivy Bridge processors will be available starting in the second quarter of 2012, which corresponds to the earlier rumors of a delay launch until April-May. The first models will be the Core i3-32xx, i5-3450, i5-3550, i5-3570K, i7-3770 and i7-3770K. In the third quarter of 3470 processors i5-i5-3570 and will be replaced by 3450 and i5-i5-3550, and a faster chip Core i7-37x0K replace the model i7-3770K.
In the third quarter and will continue to release new models of Core i3. In the last quarter of the year the same range of Intel will remain unchanged, except for withdrawal from the market of processors Core i3 architecture Sandy Bridge. As for the line of processors Sandy Bridge-E LGA for 2011, then 2012 will be released only one younger 4-core model i7-3960X.
Leaked internal materials, Intel also disclosed details about the performance of processors Ivy Bridge, which the company is evaluating dedicated several slides. Coming architecture, but in general will is translated into a 22-nm process technology Sandy Bridge, but all the time, Intel will make it a series of small changes that contribute to an increase in computational capabilities.

Desktop platform Maho Bay will be represented by a set of system logic Intel 7-Series, which will be only two new features: USB 3.0 controller and a more powerful built-in graphics accelerator with support for 3 monitors on display. Of course, the latter possibility is not meant for gaming, but rather the office work. In comparison with the 6th series chipsets only difference between the Z77 will be a new configuration of PCI Express, suggesting that a slot will have 8 lines, and the other two will use a 4-linear bus.
Most processors Ivy Bridge will receive TDP, equal to 65 W and 45 Tues A high-performance models for limiting power consumption will be 77 Tues All processors have a new integrated core Intel HD Graphics 4000 or 2500 hardware video encoding technology, Quick Sync 2.0 and support for OpenCL. For PCI Express 3.0 as long as there is no accurate data, but unofficial information indicates that Intel is currently facing in this regard with some problems, because of what the motherboard will be able to provide technical work of the third generation bus, but at least the first processors will be deprived of this technology. By analogy with Sandy Bridge is hoped that some models of Ivy Bridge, entry-level Core i3 will receive in the future accelerator HD Graphics 4000 instead of HD 2500.
Performance Comparison of Intel’s new architecture implemented on the example of processors, of which we shall test only two chips: Core i7-2600 – representative of the family of Sandy Bridge – and Core i7-3770, belongs to a generation of Ivy Bridge. The main characteristics of the processor (frequency, number of cores and the amount of cache memory) are identical, the difference lies in the integrated graphics core and the small improvements made to the CPU.
The package ArcSoft MediaConverter 7 new processor showed 56% advantage over its predecessor, transcoding a 10-minute HD-video. Testing in the pact 3DMark Vantage showed a general superiority at 2.5 to 3 times – most of the merit, of course, belongs to the IGP, but walked Sandy Bridge CPU at 17%. It is worth mentioning that the graphics core HD 4000 has a 200 MHz lower frequency compared to the HD 2000, even in the Turbo.
Other tests carried out in batches SYSmark 2012, HDXPRT 2011, Cinebench 11.5, ProShow Gold 4.5 and Excel 2010, show that made in the Ivy Bridge architectural changes, as well as higher frequencies due to Intel Turbo Boost 2.0 provides productivity growth from 7% to 15 %. Excel is able to use the faster cache memory Core i7-3770, so that the superiority of 25%. Testing the Core i5 compared with the same processor, the current generation of displays about the same rate of growth of computing power.
Thus, formal tests of Intel shows that the new generation of processors Core iX enables improved operational efficiency, which can not be considered significant. Marked improvement in the graphics capabilities of the future have the chips, but they are not so high, when compared with HD 4000 HD 3000. However, the main difference, as befits a production cycle Intel «Tick», is the new 22 nm process and lower power consumption, which will increase the battery life of laptops and ultrabukov and technology cTDP provide high performance while running on the network due to overclocking. More significant changes in the Intel is expected only in 2013 with the release of the new architecture, codenamed Haswell.
