Specifications of Haswell Refresh CPUs

In the past few years we got accustomed to Intel launching new microarchitecture each year, using new technologies and core enhancements, as well as clock speed increases to boost performance of each new generation of chips. The things will be slightly different next year, because, with the exception of some unlocked Broadwell-K models, desktop Intel microprocessors will still be built on Haswell architecture, and the only new features will be introduced in 9-series chipsets. Nonetheless, the CPUs will get a clock speed boost, which, according to VR-Zone, will be very minor, only 100 MHz over this year models.

The first Haswell refresh processors for socket 1150 will be non-"K" models, such as Core i5-4460, i5-4590, i5-4690, and Core i7-4790. All 4 processors incorporate 4 CPU cores, HD 4600 graphics, and they support DDR3-1600 memory. The CPUs are going to replace Core i5-4440, i5-4570, i5-4670 and i7-4771 SKUs. The only improvement in new products is a 100 MHz higher clock speed, which should result in up to 3% better performance.

The flagship model, the i7-4790, has Hyper-Threading technology enabled, and it packs 8 MB L3 cache on the chip. The CPU runs at 3.6 GHz, and up to 4 GHz when a Turbo Boost feature is activated. The GPU on the Core i7-4790 is clocked at up to 1.2 GHz, that is the same as on the Core i7-4771.

Core i5 microprocessors have smaller 6 MB L3 cache, and they do not support Hyper-Threading feature. The i5-4440, i5-4570 and i5-4670 operate at 3.2 GHz, 3.3 GHz, and 3.5 GHz, and have the maximum Turbo Boost frequency of 3.4 GHz, 3.7 GHz and 3.9 GHz respectively. The maximum graphics unit speeds of these CPUs are identical to GPU speeds of their predecessors.

Core i5-4460, i5-4590, i5-4690 and Core i7-4790 will be available in the second quarter of 2014. Intel will also release one "S" and two "T" low-power SKUs. "K" series CPUs with unlocked multiplier should debut in the third quarter of 2014. Known specs of future Haswell refresh CPUs are provided below (new processors are in bold):

4790K not far away?

2013-12-20 11:45:28
Posted by: Patrick

Now we have the 4790 so 4790K will be released soon or Intel will just keep 4770K there cause it has unlocked cores so can get better performance by Overclock? It kind of remind me the first gen Intel Core i7 CPUs that has i7 890 and the i7 875K, same story will happen here?
