Intel Core i7-3770K Review

Last Updated on by King Iphy

The Intel Core i7-3770K is amongst the fastest of its generation. 

At the same time, the new AMD FX 8150’s underwhelming performance means it won’t be able to compete with the Intel Core i7 3770K.

To begin with, Intel Core i7 3770K retains four cores. It’s also not clocked higher than 2700K. This is unique since it employs Intel’s brand new 22nm technology, which has 3D Tri-gate transistors. You may think that going from 32nm to 22nm would mean more cores and greater clock rates.

This is not the case, though. However, you do get Intel’s latest HD Graphics upgrade.HD Graphics 4000 is the new moniker for it, and it adds four extra execution units for a total of 16, as well as Direct X 11 support.

Features and Chipset

Sandy Bridge-based chips were available in three flavors: one quad-core and two dual-core. In a 216 mm2 piece of silicon, the most complicated implementation had 995 million transistors. The massive Ivy Bridge die, on the other hand, contains 1.4 billion transistors on a 160 mm2 die.

Most of the improvement is due to the rise in execution units, which Intel claims may enhance 3D performance by up to 2x. Execution units are programmable shaders that are responsible for graphics processing. The HD Graphics 3000 in Sandy Bridge employed 12 EUs, while the HD Graphics 4000 at Ivy Bridge employs 16. In addition, the HD Graphics 4000 supports DirectX 11, three display outputs, OpenCL and DirectCompute, and improved Quick Sync performance. The Core i7-3770K is a quad-core, Hyper-Threaded processor with 8 MB of shared L3 cache divided into four 2 MB slices, the same as the Core i7-2600K we examined a year ago.

A few modest changes have been made to the cores’ capabilities. According to Intel, these changes, together with improvements to the cache and memory controller, allow this design to execute more instructions per clock cycle.

Ivy Bridge is an Intel CPU architecture that is highly integrated. The IA cores were produced by engineers in Israel, while the graphics engine was designed by a couple in Folsom, CA. The interconnects, cache, and system agent was built by the second team in Folsom. Of course, a team of process engineers in Oregon ensured that everything would work out on the new 22 nm node.

Performance of Intel Core i7-3770K

This same Intel Core i7-3770K is the most powerful LGA1155 CPU for Ivy Road desktop PCs. The four cores can handle up to eight threads in parallel thanks to Hyperthreading, resulting in greater CPU usage. Each nature has a basic clock speed of 3.5 GHz, but with Turbo Boost, it may dynamically raise clock rates to 3.7 GHz (for four active cores), 3.8 GHz (for two active substances), and 3.9 GHz (for one active core). The “K” series CPUs also include an unlocked multiplier for simple overclocking.

Ivy Bridge is a Sandy Bridge chip redesign with improved GPU and CPU performance. The processors have a 22nm manufacturing process (versus 32nm Sandy Bridge CPUs). In comparison to Sandy Bridge CPUs with identical clock speeds, they are the first to use 3D transistors for improved energy efficiency. PCI Express 3.0 and DDR3(L)-1600 support are two more new features.

Due to minor architectural enhancements, the Core i7-3770K performs somewhat better than a comparably clocked Sandy Bridge CPU. As a result, the Core i7-2700K outperforms the Core i7-2600K by around 10%. The Core i7-3770K is much faster than AMD’s fastest desktop CPU (FX-8350).

The Intel HD Graphics 4000 GPU has 16 Execution Units (EUs) that may be tuned at 650 MHz to 1150 MHz with Turbo Boost. In modern games, the performance is only adequate for low resolutions and details.

The combined power usage of the CPU, graphics, and memory controller is rated at 77 watts by Intel (TDP).

Pros and Cons of Intel Core i7-3770K

Pros Cons
  • In comparison to the previous generation, GPU performance has dramatically improved.
  • DirectX 11 is supported
  • The skill level of the drivers has increased.
  • The manufacturing process for 22 nanometers (nm) is described below.
  • Turbo Boost adjusts the graphics clocks dynamically.
  • No sound at all
  • HDMI Supported for audio bitstreaming
  • Z68series motherboards support Intel HD4000 iGPUs, which are significantly faster than HD3000.
  • GPU performance is limited.
  • There is no specialized GPU memory.
  • There are still just 16 PCI-E lanes available.
  • Early manufacturing stepping isn’t as good at overclocking as the present Sandy Bridge.
  • Not a great leap forward over Sandy Bridge, with average air overclocking potential.
  • On the highest-end last-generation CPU, it provides only slight performance increases; graphics are still inferior to those provided by a separate video card.

 

Conclusion

The Intel i7-3770K CPU’s overall performance, thanks to its enhanced new CPU design, leads us to classify it as biased for multi-threaded workloads. Power users and enthusiasts who seek workstation-like performance and power optimization balance will like it. It’s a delicate balance to strike, and we believe the Intel Core i7-3770K achieves it with ease.

Ivy Bridge appears to be the platform of choice for most people for the remainder of the year (not that they have many alternatives), based on what we’ve seen from the Core i7-3770K, and additional varieties of it will follow suit for desktop and mobile devices. It isn’t very beautiful, but the renovations it has received in general add to its charm.

Nevertheless, Ivy Bridge CPUs will not appeal to the core enthusiast DIY market, which is likely to already be utilizing a Sandy Bridge level processor. This is due to the fact that the noticeable gains are tiny when compared to one another. You’d think that the 22nm production would allow it to stretch even farther, but overclocking appears to be limited, since high speeds soon produce hot patches, which slow down the processor’s overall performance. We’re not saying Ivy Bridge is bad, but because it’s compatible with most Sandy Bridge systems, it won’t appeal to the same folks it was designed for.

Ivy Bridge is a pleasant update, but it isn’t a fantastic one, as we previously stated. Like we mentioned earlier, Ivy Bridge is a pleasant update, but it’s not a stellar one.
