Overall Haswell has further strengthened Intel’s position providing greater performance, efficiency and features. It might only be a mild step up from what we had with Ivy Bridge, but at $339 the Core i7-4770K is roughly the same price as the i7-3770K.

When Intel talked about Haswell during IDF 2012, the chipmaker pointed out that it will have 5%- 15% gains over Ivy Bridge when set on same clocks, but Intel was aiming to gain big gains in lesser power consumption, especially for notebooks and smaller...

It has taken just about two years' time, but today the moment has come for Intel to update its high-end consumer platform. The Sandy Bridge-E models Core i7 3960X, 3930K and 3820 will be retired, to be replaced by Ivy Bridge-E, as represented by the...

Recently we've tested Intel's first processor based on Haswell architecture and we've come to a conclusion that it didn't bring anything new. A total of 10% increase in performances compared to its predecessor in processor tests, while the only big...

At this article's outset, we established all of what makes Intel's Haswell architecture so noteworthy. We always expect performance to be improved from one architecture to the next, and of course, we expect the same for power-efficiency. Here, though,...

Late May we published a huge round-up of 45 desktop processors , followed by a review of Intel's fourth generation Core processors . Our readers immediately, and understandably, came with the request for a similar group test of laptop processors. It's...

It is that time again, when the eighteen month Moore's Law clock hits zero and the next generation of CPU hardware arrives, fulfilling the promise of a doubling of transistors with each cycle. Known until now by the codename Haswell, Intel's...

Overall, the new processor provides some decent performance increases in just about every department but Haswell is hot! In fact, it’s making Ivy Bridge look cool, both literally and in many other regards, like making it OK to stay with it for now....

As many in the home theater PC (HTPC) community are aware, madVR produces an unparallelled level of flexibly and performance. Producing results that rival some of the best dedicated video processors available in the market. It was not that long ago that...

For the Jacobi Successive Over-Relaxation test in SciMark2, the performance is noticeably superior on LLVM/Clang. For the Himeno scientific workload, LLVM/Clang is slower than GCC and unfortunately with the new LLVM/Clang 3.3 the performance had...

When a new processor from Intel comes out many people are expecting a huge improvement over the previous generation, but we lately we really have not seen that. If you look at the update cycle of 1 year that cannot be expected. Ivy Bridge only...

Intel's new Haswell based Core i7 4770k is a solid CPU, but as we can see from some of the tests not every piece of software will be able to take advantage of what it has to offer. There is also the possibility that motherboard makers will need to tweak...

While some computationally-intense applications are benefiting greatly from the core-avx2 compiler optimizations, not all workloads will benefit. The core-avx2 instructions also caused some performance regressions with what's found in GCC 4.8.1. GCC...

With the high-end CPU race firmly in their pocket, Intel didn't need to light the world aflame with a significantly faster processor. Breathing room is a luxury few technology companies can claim and its given Intel time to improve their products...

While there isn't a substantial increase in GPU performance between Richland and Trinity, AMD's GPU performance lead over Ivy Bridge was big enough to withstand Haswell's arrival. Note that although we're comparing performance to Haswell here, Richland...

Final Thoughts ]In terms of performance the upgrade to Haswell is very reminiscent of that from Sandy Bridge to Ivy Bridge, in the sense that for the most part we only saw a very minor improvement in performance. Where Haswell looked most impressive...

For the multi-threaded C-Ray ray-tracer, none of the tested CPUs come close to matching the i7-4770K's performance-per-Watt under Linux. Stay tuned for additional Intel Core i7 4770K "Haswell" benchmarks under Linux coming soon on Phoronix. No...
