Intel Core i7-4790 (Haswell Refresh) Review




Some users prefer a processor that can be overclocked, while some are already content with what it can do right off the bat. If you belong to the latter group, then you’ll probably want to take a look at the Intel Core i7-4790 which is one of the many processors in the Haswell Refresh lineup that was launched earlier this year.

Intel Core i7 4790 philippines

Overview and Key features

Prior to the launch of the Haswell-E family, the i7-4790 was the raw version of Intel’s flagship processor under the Haswell architecture. It’s not overclock-able like the 4790K, and it has a higher TDP compared to its low-power siblings such as the 4790S and 4790T.

It does, however, share a lot of similarities with the other variants of 4790 including LGA 1150 socket, Intel HD Graphics 4600, L2 Cache (4 x 256KB) and L3 Cache (8MB), as well as support for Intel technologies such as vPro and TXT that are not present on its “K” counterpart.

Specs-wise though, the 4790 doesn’t offer a lot of new things on the table that we haven’t seen on its predecessors (4770 and 4771) apart from a slightly higher stock frequency which is rated at 3600Mhz and higher Turbo Boost speed (4000MHz).

Performance and Benchmark

As one can expect from a top-of-the-line processor, the i7-4790 was able to comfortably handle pretty much whatever we threw its way. Whether we’re gaming on it or using it for fairly demanding productivity software, the processor didn’t buckle even one bit and provided a very respectable performance all throughout.

3D Gaming Performance

In addition to the benchmark tests we performed on the i7-4790, we also tried playing a few games to measure how well can the chip’s iGPU (Intel HD 4600 Graphics) handle such task. Spoiler, it’s nothing to write home about.

Benchmark Result Analysis / Conclusion

Based on the data we gathered on various benchmark tests that we ran using the i7-4790, we were able to validate two things. First is how pedestrian the performance of the iGPU on this chip and, second, how much firepower each of the 4790’s core can spit out at any given time.

One can probably forgive the lackluster performance of the HD 4600 Graphics on gaming since we would assume that users are most likely to pair this processor with a dedicated graphics card. In fact, scratch that part, you owe it to yourself to purchase a decent GPU if you’re planning to play demanding games with this processor!

Intel Core i7-4790 specs:

Processor Family: Haswell-DT
LGA 1150 Socket
H81, B85, Q85 Q87, H87, Z87, H97 & Z97 Chipsets
3.6GHz Core Clock, 4.0GHz Turbo Frequency
Quad-core processor with eight (8) threads
L2 Cache: 4 x 256KB
L3 Cache: 8MB
Support for dual-channel 1333 / 1600MHz memory modules
Up to 32GB DDR3 RAM
Integrated Intel 4600 HD Graphics
350Mhz Base Frequency, up to 1.2GHz Dynamic Frequency
Supports up to 3 displays
84-watt Max TDP
Support for vPro, Hyper-Threading and Turbo Boost Technologies
Intel Virtualization Technology (VTR-d, VT-x & VT-x w/ EPT)

On the brighter side, users will truly be satisfied with what the i7-4790 can offer in terms of processing power. Yes, the 200Mhz and 100Mhz speed bump on the core clock speed and Turbo frequency respectively may make this chip a tough buy for current i7-4770 users, but it should be enough to convince i7 Sandy or Ivy Bridge users to make the jump.

To conclude, the Intel Core i7-4790 is the best locked processor that the chipmaker currently has to offer. The increase in core and turbo frequencies may seem nominal on paper, but should be a welcome addition nonetheless considering that it’s priced the same ($312 Boxed / $303 Tray) as the processor it replaced. It’s also loaded with all the latest and greatest optimizations, tweaks and technologies from Intel which should come in handy for added boost in performance and stability.

Just to reiterate, this processor is intended for users who are, by no means, interested about overclocking. If you have, however, even a slight hint of curiosity about overclocking, then you’re better off getting the 4790K which only costs less than two thousand pesos more.

What we liked it about it:

* Slight increase in core and turbo frequencies
* Decent Turbo Boost frequency
* Excels in CPU-related tasks
* Relatively low power consumption
* Support for Intel XMP
* Doesn’t require high-end RAM for performance boost

What we didn’t like about it:

* Poor iGPU performance in gaming
* Not much to offer from the previous gen
* Somewhat sucky stock cooler

    I just had a local shop custom-build me a PC desktop with this same exact CPU. Paired with a Palit GTX 750Ti StormX Dual GPU, there is not much problem with gaming from what I have tried. The only problem I had with it so far is the somewhat inefficient stock Intel CPU cooler which makes the CPU temperature reach a temperature of 60 degrees Celsius even at minimal load (minor applications, no gaming). Note also that we’re still in the “ber” months of the year at that rate which also means that the surrounding temperature can get hotter during the summer.

    How much is the building this PC?

    try to use an after market cpu cooler. if you have enough dough, why not get a cooler master liquid cooling ?[should be running around 6k to 8k dependent on the model you would get].
