Intel Haswell Makes Its Debut: Core i7-4770Okay Evaluation

Regular Catrachadas readers will no doubt have seen several Haswell mentions on our front page this year. In the past few months, we've covered everything from model names to performance and battery life information. The main focus was on Haswell's graphics. Rumor has it that the performance will be two to three times higher than that of the current integrated HD 4000 graphics.

What is Haswell? It is Intel's 4th generation core architecture, which in 2013 will experience a comprehensive refresh of the entire Core i3, Core i5 and Core i7 product range, more significant progress forward.

Efficiency and graphics have continued to be a focus for Intel in recent generations, and Haswell is no different. Intel claimed that Ivy Bridge was a "tick +" because the graphics side of things had been completely redesigned. Although it offers up to twice as much graphics performance as Sandy Bridge in certain circumstances, 3D rendering performance was still very low compared to discrete solutions.

And the time has finally come. Haswell is ready to be launched along with the latest Intel on-die GPU solutions. Today we're just going to test the new HD 4600 graphics, which are part of the high-end desktop processor Core i7-4770K. Starting today, faster HD 5000 Graphics and Iris Graphics 5100 and 5200 solutions are also available. As expected, the most powerful integrated graphics solutions are reserved for processors developed for mobile devices such as Ultrabooks.

4th generation Intel Core CPU family

The Haswell range consists of several desktop and mobile Core i7 and Core i5 processors, which effectively replace most of the current offers in this series. Core i3 variants will be launched later in the year.

The new Core i7 desktop processors include the Core i7-4770K, i7-4770R, i7-4770T, i7-4770S, i7-4770 and i7-4765T – all for $ 303 except the i7-4770K, which sells for a small premium at $ 339. The Core i7-4770K and the i7-4770 are identical in almost every respect with a few 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 i7-4770S and i7-4770T are members of the low-power series, and as such, the TDP has been reduced from 84 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 i7-4770S and to 2.50 GHz for the i7-4770T.

All Haswell Core i7 desktop processors have 4 cores with 8 simultaneous threads when using Hyper-Threading. The Core i7-4770K operates 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 / 1600 memory and have an 8 MB L3 cache.

The most interesting product of the Core i7 series is the 4770R, which works at 3.20 GHz and a turbo frequency of 3.90 GHz and uses the BGA package. This model outputs the HD 4600 graphics that are used by all other Desktop Core i7 processors and opts for the more powerful Iris Pro Graphics 5200 instead. The only disadvantage of this chip is the reduction of the L3 cache from 8 MB 6 MB.

Intel also offers a lower clocked model, the Core i7-4765T, which has a TDP of only 35 watts and is clocked at only 2.0 GHz and a maximum turbo frequency of 3.0 GHz.

Then there is the new Core i5 series with the processors i5-4670K, i5-4670 and i5-4570 at a price of $ 242, $ 213 and $ 192 respectively. There are also models Core i5-4670T, i5-4670S, i5-4570S, i5-4570T and Core i5-3450S with low power consumption. We know it will be very confusing. So let's talk about the standard processors first.

All standard Haswell Core i5 processors have an 84 W TDP and have four cores and four simultaneous threads. The only Core i5 processor that differs from this configuration is the dual-core i5-4570T with four-thread hyper-threading.

The Core i5 range is clocked aggressively: The i5-4670K and the i5-4670 operate at 3.40 GHz and a Turbo Boost frequency of 3.80 GHz. Meanwhile, the i5-4570 is clocked at 3.20 GHz and a turbo frequency of 3.6 GHz.

All Core i5 processors have a 6 MB L3 cache, with the exception of the i5-4570T, which has been downgraded to 3 MB. All Desktop Core i5 processors use the HD Graphics 4600 engine without exception.

The power-saving Core i5 series is just as confusing. The four models available at launch are different, although many of them have the same price range. The Core i5-4570T is essentially a Core i3 processor with Turbo Boost. This processor works at 2.90 GHz and a Turbo Boost speed of 3.60 GHz. Like the Core i3 processors, the i5-4570T has only two cores with Hyper-Threading support and a smaller 3 MB L3 cache. It is said to cost $ 192.

Then there is the Core i5-4670T and the i5-4670S (both $ 213). The i5-4670T has a thermal design of 45 W and works at 2.30 GHz and a turbo boost frequency of 3.30 GHz. The i5-4670S is actually faster and works with a base clock of 3.1 GHz and a turbo boost frequency of 3.8 GHz. As expected, the i5-4670S has a higher TDP power of 65 W.

Finally, we have the Core i5-4570S and i5-4570T processors (both $ 192) with a TDP power of 65 W and 35 W. Both CPUs have a base clock of 2.90 GHz with a Turbo Boost Frequency of 3.60 GHz.
