Since the end of last year, Ivy Bridge seems to be the architecture everyone is waiting for. Although Intel only expects processing performance to be reduced by 10-15% compared to Sandy Bridge, the big news comes in the form of improved graphics and efficiency thanks to the switch to a 22nm design process using the new 3D transistor technology we offer have recently explained detail here.
Today, the company introduces its new line of Core i7 and Core i5 processors that accompany chipsets and wireless Centrino options. Ivy Bridge is a "tick" version, but Intel calls it a tick + as the graphics side of things becomes more and more important. The new chips are said to offer 20-50% better GPU performance than Sandy Bridge, the kind of jump we would normally expect from a token release.
To be fair, Intel has had a matte GPU performance for its integrated chipsets for years. When they put the GPU on the chip, they continued to perform the same below-average performance, and they are lagging far to date, but that doesn't mean that things haven't changed dramatically for the better. Features and performance have been scaled to such an extent that integrated graphics can display high-resolution content, more than one screen, process multiple inputs and offer wireless display technology, among other things.
Intel is preparing another big surge in graphics performance when the Haswell architecture launches next year. In the meantime, consumers should watch for the same money for faster performance and even better efficiency of the Ivy Bridge architecture.
For a while, the switch to the new manufacturing process seemed to cause a delay of several months, but the company was able to reduce it to a few weeks. As you know, the release of the Ivy Bridge chipset remained on track. The new 7 Series chipsets are backward compatible with Sandy Bridge processors, making it possible to buy a Z77 motherboard and use it for a few weeks now.
After thoroughly discussing the new tri-gate transistors, the new 7-series chipsets, and some of the motherboards that use them, the main focus of this review will be on the Core i7-3770K processor.
3rd generation Intel Core Lineup
The Ivy Bridge range consists of several desktop and mobile Core i7 and Core i5 processors, which effectively replace most of the current offerings in this series. Core i3 variants will be launched in the second half of the year.
The new Core i7 desktop processors include the Core i7-3770K, i7-3770, i7-3770T and i7-3770S – all for $ 278, with the exception of the i7-3770K, which costs a light $ 313 premium -Dollar is sold. If you ask us, it's a bit like the unnecessarily diverse versions of Windows Vista / 7, but that's how Intel handles its CPUs these days. The Core i7-3770K and the i7-3770 are identical in almost every respect, with a few important exceptions. The K version is delivered with an unlocked multiplier and is immediately 100 MHz faster. The Intel vPro / TXT / VT-d / SIPP technologies have also been removed from the K series.
The Core i7-3770S and the i7-3770T are members of the low-power series (second table below). The TDP was therefore reduced from 77 W to 65 W and 45 W, respectively. A decisive factor for this lower consumption is a lower CPU base frequency, which is reduced from 3.50 GHz to only 3.10 GHz for the i7-3770S and to 2.50 GHz for the i7-3770T.
All Ivy Bridge Core i7 desktop processors have 4 cores with 8 simultaneous threads when using Hyper-Threading. The Core i7 3770K works at 3.50 GHz and a Turbo Boost frequency of 3.90 GHz, while the non-K version offers the same Turbo Boost frequency with a base clock of 3.4 GHz. They are designed to work with DDR3-1333 memory and have an 8 MB L3 cache.
Then there is the new Core i5 series with the processors i5-3570K, i5-3550, i5-3470 and i5-3450 ($ 194 for the K version, $ 174 for the rest). There are also models Core i5-3570T, i5-3550S, i5-3470T, i5-3470S and Core i5-3450S with low power consumption. We know this will be very confusing. So let's talk about the standard processors first.
All standard Ivy Bridge Core i5 processors have a 77 W TDP and have four cores and four simultaneous threads. The only Core i5 processor that differs from this configuration is the dual-core i5-3470T with four-thread hyper-threading.
The Core i5 range is clocked aggressively: The i5-3570K and the i5-3570 operate at 3.40 GHz and a Turbo Boost frequency of 3.80 GHz. The i5-3550 works at 3.30 GHz and a Turbo Boost speed of 3.70 GHz, the i5-3470 has a base clock of 3.20 GHz and can reach 3.60 GHz when using Turbo Boost.
Finally, the Core i5-3450 has a base clock of 3.10 GHz and a turbo boost frequency of 3.50 GHz. All Core i5 processors have a 6MB L3 cache except for the i5-3470T, which has been downgraded to 3MB.
All Core i5 processors use the Intel HD Graphics 2500 engine, with the exception of the i5-3570K, which uses the HD Graphics 4000 engine.
The power-saving Core i5 series is just as confusing. The five models available at launch are different, although many of them have the same price range. The Core i5 3470T is essentially a Core i3 processor with Turbo Boost. This processor works at 2.90 GHz and a Turbo Boost speed of 3.50 GHz. Like the Core i3 processors, the i5 3470T has only two cores with Hyper-Threading support and a smaller 3 MB L3 cache. It is said to cost $ 174.
Then there is the Core i5-3570T and the i5-3550S (both $ 194). The i5-3570T has a thermal design of 45 W and works at 2.30 GHz and a turbo boost frequency of 3.30 GHz. The i5-3550S is actually faster and works with a base clock of 3.0 GHz and a turbo boost frequency of 3.37 GHz. As expected, the i5 3550S has a higher TDP power of 65 W.
Finally, we have the Core i5-3470S and i5-3450S processors (both $ 174) with a TDP power of 65 W. The Core i5-3470S has a base clock of 2.90 GHz with a Turbo Boost Frequency of 3.60 GHz, while the i5-3450S works with 2.80 GHz and a turbo boost of 3.50 GHz. Like the Core i7-3770K and the i5-3570K, the i5-3450S also lacks the Intel vPro / TXT / VT-d / SIPP technologies.
