Intel released two Devil Canyon processors; Intel Core i7 4790K and the Intel Core i5 4690K in early June 2014. The two CPUs are different from the general K-series chips because they have newer thermal interface material that is meant to lower temperatures by providing an advanced conduit between core and heat spreader. They also are capable of accommodating extra capacitors that provide stable voltage regulation at higher frequencies.
The Intel Core i5-4790K tops most of benchmarks, overlocks like the Intel Core 4790K and runs a lot cooler. It is however more pricier than the Pentium G3258 but is one of the fastest CPUs tested so far.
With the 4690K review we get extra 100 MHz speed boost over the Intel Core i5 4670K both at default frequency and 3.5 GHz and 3.9 GHz when Turbo Boost. It has an increased Thermal Design Power (TDP) of 88 W which is higher than the 84 W of its predecessor Intel Core i5-4670K.
Compared to its predecessor once more, they have the same specification of 6 MB Level 3 cache, four physical cores with Hyper-Threading disabled and Intel HD Graphics 4600 with 20 execution units and 1,200 MHz core speed. Both the core i5-4690K and the Core i5-4670K support TSX-NI and VT-d. In addition, the Intel Core i5-4690K has 256 KB L1 Cache, 1 MB L2 Cache and 1.5 MB/core L3 Cache.
Features and chipset
Both Intel Core i5-4690K and the Core i5 4670K reviewed feature the LGA1150 socket. This shows that they are compatible with 9 series motherboards and most 8 series motherboards. The Intel Core i5-4690K has dynamic frequency scaling, AES, supports hardware-assisted virtualization and AVX as well as SSE version 4.2.
The architecture features of the Intel Core i5-4670 reviews include enhanced SpeedStep technology, Execute Disable Bit capability, Intel Virtualization Technology, Intel 64 Technology, streaming SIMD extensions 4.2, Intel Turbo Boost technology 2.0 and the Intel My Wi-Fi Technology. We also have Intel Anti-Theft Technology, Intel AES New Instructions (AESNI), Thermal Monitoring Technologies, Idle States, and Intel VT-x with extended page Tables (EPT), Intel Identity Protection Technology, Intel Secure Key, Intel Advanced Vector Extensions 2 (AVX2.0) and Intel TSX-NI.
Overclocking and heat
In the Intel i5-4690K review, Intel has made some improvements especially with the Next generation Polymer Thermal Interface Material (TIM). This is aimed to improve the high temperatures experienced with previous CPUs like the Haswell and the Ivy Bridge. The addition of capacitors on the underside of the processor has played a big role in delivering smoother power.
The updated TIM has proved to offer better temperatures when overlocked and under load which is not the same case with previous models of Haswell CPUs in the Intel Core i5-4790K review. With the idle power consumption at stock speed, the Core i5-4690K was lower than Core i3-4130 at 48 W and was 30 W lower than the Core i5-4670K. Another test revealed that it was just 11 W more powerful than the Intel Core i3-4130 at stock speed. At 4.8 GHz, the additional voltage needed in reference to previous models was noticed to be between 10 and 20 W more at 180 W for the entire system.
The frequency achieved with an all-in-one closed-loop-liquid-cooler was 5.5 GHz which was stable enough for a CPU-Z screenshot with the air that goes through the radiator cooled using nitrogen liquid.
Pricing and availability
The recommended retail price of Intel Core i5-4690K is $242.00 to $243.00. The Pentium G3258 could be a great substitute if you overclock it as it is slightly cheaper however it lacks grunt in the multi-tasking section even when overlocked. The i7-4790k on the other hand clocks the same as the Intel Core i5-4690K and runs a whole lot cooler as well.
The Intel Core i5-4690K is a high-end processor that features high-end air coolers and all –in-one liquid cooler with 4.8 GHz. When we compare this to 4.8 GHz featured in Core i7 and Pentium G3258 performs better it terms of temperatures meaning they have higher overlocks compared to the Intel Core i5-4690K and Intel Core i5-4670K. If at all you have the Intel Core i5-4670K there is no need of upgrading to the next tier maybe if you want a more overlocking-friendly processor.
