Haswell Refresh: Intel Core i5-4690T Review and Testing Performance

It seems that this year Intel decided to deviate from its strategy “Tick-Tock”, where “Tick” is a change of process technology, and “Tock” the change of microarchitecture. A new family of Intel Haswell Refresh falls out of this concept, as is built on the same 22-nm process technology like Intel Haswell model and use a similar microarchitecture. The only difference is slightly higher clock rates.  Essentially processors Intel Haswell Refresh is just new stepping of Intel Haswell.So far about any new generation CPU Intel Core speech, of course, is not. In fact, we just got a lineup expansion decisions under the platform Socket LGA1150. Not so long ago the same as AMD did, releasing APU AMD Richland, which is an optimized version of APU AMD Trinity.

However Intel came to the updating processor line with a much larger scale. It has announced more than 40 new models: 27 of them for desktop configurations, and 17 for mobile. First of all we are interested in desktop versions. Their short specification and recommended price are given below:

The table shows that all categories of CPU, from low-cost Intel Celeron to “top” Intel Core i7 have got several new models. It is assumed that first time they will exist on the market in parallel with the existing processors Intel Haswell and then gradually replace them. Hopefully, this process will not have negative result on CPU cost.

Attentive readers have noticed that the list doesn’t include the products with an unlocked multiplier. And it's not a mistake, but a considered marketing idea. Optimized model with free multiplier (in the generation Intel Haswell designated with index “K”) will appear on the market but little bit later as a separate family called Intel Devil's Canyon. Intel Company has immediately declared that the optimization of overclocking CPU versions will affect not only the frequency formula but also the thermal interface. In particular it has limited the overclocking capabilities of the processor.

As for Intel Haswell Refresh solutions, nothing was changed and between the lid and the chip thermal paste is still used. New released models are fully compatible with platform Socket LGA1150 and motherboards equipped with Intel chipsets of 9 and 8 series. In the latter case it is necessary to simply update the BIOS.

Intel Core i5-4690T

There is no need to describe in details about the micro-architecture features of Intel Haswell Refresh, since it is identical to that used in the models of Intel Haswell.

For now we have Intel Core i5-4690T – energy efficiency with reduced TDP.

Appearance and technical specification

We have got test (engineer) chip without the package and cooling system that’s why the description of these items is missing.

Intel Core i5-4690T

There is no difference from its predecessors the Intel Haswell series. Over the heat distribution lid there is information about its marking, clock frequency and country of origin. Also here you can find the inscription “INTEL CONFIDENTIAL”. For retail it will be replaced by model name.

Because of a family of processors Intel Haswell Refresh platform compatible with Socket LGA1150, then the location of contacts on the back side is fully consistent with this connector.

According to specification table we can say one more time that Intel Haswell Refresh CPUs are only optimized versions of Intel Haswell. In fact, we have the complete copy of technical parameters of Intel Core i5-4670T model. The only difference is the frequency formula.

Intel Core i5-4690T

During normal operation (without Intel Turbo Boost 2.0 technology) the speed Intel Core i5-4690T is equal to 2500 MHz, supporting speed is 100 MHz and multiplier “x25”. At the time of reading of the core voltage was 0.933V.

Intel Core i5-4690T

In case if you enable the mode of dynamic frequency increase Intel Turbo Boost 2.0, then the multiplier increases by 10 points to the value of “x35”. Processor clock speed will be increased to the level of 3500 MHz, and the voltage  up to 1.201 V. This is a big difference in the frequency and voltage of the power in different modes due to the desire of manufacturers to reduce CPU power consumption for resource-demanding tasks.

At maximum loads scheme of processor cores is the following:

  • 1 core – multiplier “x35”;
  • 2 cores – multiplier “x34”;
  • 3 core – multiplier “x32”;
  • 4 cores – multiplier “x31”.

At the same time processor varies between 3100 - 3500 MHz (supply voltage also falls below 1.201V), but most of the time it spends at the rate of 3100 - 3200 MHz. All this done to reduce energy consumption and heat release.

Intel Core i5-4690T

In idle mode the multiplier is decreased to “x8” value, thus the frequency drops to 800 MHz. The voltage is 0.688 V. According to this data it became possible to understand that regarding energy saving mechanism nothing has changed compared to the CPU Intel Haswell. Lower threshold of processor cores speed is 800 MHz (standard frequency reference).

Intel Core i5-4690T

Cache Memory Intel Core i5-4690T is distributed in the same manner as for 4-core models of the family Intel Haswell:

  • L1 cache memory: each 4-core has 32 KB for data with 8 associativity channels and 32 KB for instructionith 8 associativity channels;
  • L2 cache memory: each core has 256 KB with 8 associativity channels;
  • L2 cache memory: 6 MB for all cores with 12 associativity channels.

Intel Core i5-4690T

DDR3 memory controller run in dual channel mode and supports modules with frequency up to 1600MHz. Maximum memory capacity is 32 GB.
