Performance in Applications
We’ve found out already that we can’t expect performance breakthroughs from the Ivy Bridge series. It can only offer small performance benefits compared to the previous series unless we take into account its integrated graphics core which we are going to cover in an upcoming review. Well, let’s just see what the Core i7-3770K can offer in various resource-consuming applications.
To test the processors performance during data archiving we resort to WinRAR archiving utility. Using maximum compression rate we archive a folder with multiple files with 1.4 GB total size.
As can be expected from a new product, the Core i7-3770K is a little faster than the Core i7-2700K at archiving but the quad-core Sandy Bridge-E for the LGA2011 platform is considerably faster thanks to its larger L3 cache and quad-channel memory controller.
We use Apple iTunes utility to test audio transcoding speed. It transcodes the contents of a CD disk into AAC format. Note that the typical peculiarity of this utility is its ability to utilize only a pair of processor cores.
The Core i7-3770K is 7-8% ahead of the Core i7-2700K and Core i7-3820 whereas the Core i5-3570K beats the Core i5-2500K by about 10%.
We measured the performance in Adobe Photoshop using our own benchmark made from Retouch Artists Photoshop Speed Test that has been creatively modified. It includes typical editing of four 10-megapixel images from a digital photo camera.
The new microarchitecture ensures the expected performance benefits in Photoshop CS5, so the Core i7-3770K is as fast as the Core i7-3820 while the Core i5-3570K overtakes the Core i7-2700K, a higher-class CPU of the previous generation.
Now that the eighth version of the popular scientific Mathematica suite is available, we decided to bring it back as one of our regular benchmarks. We use MathematicaMark8 integrated into this suite to test the systems performance:
The Core i7-3770K is the same 5% ahead of the Sandy Bridge Core i7 in this test, too. The Core i5-3570K beats the Core i5-2500K by almost 8%. It is the 100 MHz higher clock frequency that saves the day for the newcomer in this test.
The performance in Adobe Premiere Pro is determined by the time it takes to render a Blu-ray project with a HDV 1080p25 video into H.264 format and apply different special effects to it.
Work with video content is a type of task that allows Ivy Bridge to really shine and show its potential best of all. Core i7-3770K is almost 8% ahead of Core i7-2700K, and Core i5-3570K is as much as 16% faster than the same-class Core i5-2500K.
In order to measure how fast our testing participants can transcode a video into H.264 format we used x264 HD Benchmark 4.0. It works with an original MPEG-2 video recorded in 720p resolution with 4 Mbps bitrate. I have to say that the results of this test are of great practical value, because the x264 codec is also part of numerous popular transcoding utilities, such as HandBrake, MeGUI, VirtualDub, etc.
The x264 transcoding test produces the same results as the previous benchmark. The Ivy Bridge series enjoys a 10-15% advantage over the second-generation Core CPUs.
Following our readers’ requests, we’ve added a new HD video benchmark to our tests. SVPmark3 shows the computer performance in the SmoothVideo Project application which makes videos smoother by adding new intermediary frames. The numbers in the diagram reflect the speed of processing Full HD videos without the graphics card’s help.
Here is another result that fits the overall picture perfectly. The Core i7-3770K is at the top of the diagram, being only inferior to the six-core LGA2011 processor. In other words, the senior model of the Ivy Bridge series is one of the fastest quad-core CPUs available today.
We will test computational performance and rendering speeds in Autodesk 3ds max 2011 using the special SPECapc for 3ds max 2011 benchmark:
The new CPUs deliver high performance in workstation applications but the difference between the Core i7-3770K and Core i7-2700K, and between the Core i5-3570K and Core i5-2500K, is smaller than usual.
Another benchmark measuring the final rendering speed in 3D modeling suites was run in Blender 2.6.
When rendering in Blender, the Core i7-3770K is 9% ahead of the Core i7-2700K. The Core i5-3570K, in its turn, is 10% faster than the Core i5-2500K.
Having benchmarked the Ivy Bridge series in over 10 different applications, we can say that it’s always faster than the Sandy Bridge CPUs with the same specs. The advantage amounts to an average 6%.
Moreover, the Core i7-3770K is often superior to the Core i7-3820, a higher-class product for the LGA2011 platform, in applications that are not memory-intensive. In other words, the Core i7-3770K seems to have no worthy quad-core opponents in terms of computing performance.
