Two of the most-sought processors in the market today are Intel i7 4790K and Intel Core i5 7600K. If you plan to purchase one of these processors, it is important to understand their differences and similarities to help you come up with the smart decision.

Which processor should you buy? Let’s check the main features of Intel i7 4790K and Intel Core i5 7600K. Know the differences between the two and the important things you need to consider before buying one.

Intel Core i5 7600K vs i7 4790K

Features and Specs

The Intel Core i5 7600K is a 3.8 GHz with Intel Core i5, whereas Intel i7 4790K is 4.4 GHz with Intel Core i7. The Intel i7 4790K was first released in the market as compared to i5 7600K, both with similarities and differences.

Raw Performance Index

Intel Core i5 7600K

When it comes to the raw performance index, Intel Core i7-4790K has a better raw single-thread and multi-thread performance estimation as compared to Intel Core i5-7600K. It means that multi-tasking is better with Intel Core i7-4790K, whether you are encoding, video streaming, surfing, and checking your emails at the same time.


In terms of architecture, Intel Core i7-4790K is made of Intel_Haswell, whereas Intel Core i5-7600K possesses an Intel_Kabylake. The memory support of Intel Core i7-4790K is DDR3, while Intel Core i5-7600K has DDR4. An upgrade to Kabylake provides a better performance, most especially if you are having problems with your CPU, most especially the RAM. If you just do surfing and basic gaming, keeping Haswell is a good idea.


Intel Core i7 4790K

Micro-Processors have cores, and the more cores a processor has, the better. Just think about your kitchen stoves as cores. If you have more than one stove, you can cook food at the same time. Same is true with processors. So, you want more cores and more threads because it means smoother and faster running applications.

The same is true if your processor a higher number of core, the processing of tasks and applications will be smoother and you can also run more threads smoothly, thus making applications faster. Both processors have 4 cores. The great Intel Core i7-4790K has 8 threads, while Intel Core i5-7600K has 4. For integrated graphics, Intel Core i7-4790K has Intel HD 4600, whereas Intel Core i5-7600K has Intel HD Graphics 630.


A cache refers to the auxiliary memory to make high-speed information retrieval possible. Cache is placed between the CPU and RAM because CPU has a faster access. The higher the number, the better cache the processor has. It only means that retrieving data is smoother and faster without compromising overall performance. Although cache functions are not really noticeable, people who use a lot of applications and complex software will notice the difference.

For L1 and L2 cache, both processors have 64 KB per core ad 256 KB per core respectively. The L3 of Intel Core i5-7600K has 6144 KB shared, while Intel Core i7-4790K has 8192 KB shared.


When it comes to the socket, it is considered as the physical interface in which a processor is connected to. New processors today are requiring different pins, so it means, a new socket emerges.

These sockets are located on the motherboard of a computer, and they cannot be upgraded. It is only possible if you change the entire motherboard. That’s why if you upgrade to a new generation processor, it would require a complete rebuild of your system. This is the reason why you need to know the socket of your computer system.

The Intel 1151 design supports 6 different chipsets in total, including Q170, H170, Q150, B150, and H110 (highest to lowest), and so as Z170, which has the highest performance. The Intel Socket of Intel Core i5-7600K is 1151. On the other hand, has 1150 Intel Socket. The Intel Socket 1150 is found on 6 different chipsets including Z87, H87, Q87, Q85, B85, and H81, wherein the last three are the entry-level line. The Intel 1151 is now the latest socket design of Intel, supporting connections with USB 3.0 and faster DDR4 RAM. The Intel 1150 is an entry-level line, so it does not support Smart Response and Intel Rapid Storage.


When it comes to the turbo clock speed, Intel Core i5-7600K has 4000 MHz, and 4400 MHz for the older processor, Intel Core i7-4790K. Both have a base clock of 100 MHz. The CPU frequency of Intel Core i5-7600K is 3800 MHz, and 4000 MHz for the older Intel Core i7-4790K. The higher the number, the better is the performance.


When it comes to the features, both have the same features except for some. The Intel Core i7 4790K has additional features including VT-d, TSX, HTT, and TXT. Both processors have a maximum case temperature of 72°C.

Which Processor to Buy?

To summarize everything, here are the important points you need to remember before buying the best processor for your needs. Intel Core i5 7600K is a newer product as compared to Intel i7 4790K with a better performance and compatibility. On the other hand, Intel Core i7 4790K has a single thread performance, which is higher by 18 %. The multi-threaded great performance is also higher by 32%, allowing better performance when multitasking or encoding. It also has a higher synthetic performance by 27%.

When choosing between the two, it all depends on your needs. If you want superior performance you can take advantage when multitasking, the Intel Core i7 4790K is for you. If you want to explore the advantages of a newer version of a processor with greater compatibility array, then the Intel Core i5 7600K is best for you. At the end of the day, the final say relies on you based on your needs and expectations.
