Ivy Bridge Core i5-3570K (left)
Several days ago, our colleague Henry posted two CPU pictures in the forum, Could you guess exactly what they are? Now let’s disclose the answer. They are all ES (Engineering Sample). The CPU on the right is Core i5-2500K, while on the left is the upcoming Ivy Bridge Core i5-3570K. You may also want to know what performance this Ivy Bridge processor will have, later we will present more test to you, today let’s see how much change with its IGP (Integrated Graphics Processor) performance.
As we could see from the CPU-Z 1.59 screenshots shown above, Core i5-3570K features the close specs with the current Core i5-2500K, but its process has been updated to 22nm, and default frequency improves to 3.4GHz, as well has TDP of 77W.
The IGP is Intel HD Graphics 4000, which is also applied in the K-series processor and some Ivy Bridge processors. According to the leaked information in IDF (Intel Developer Forum) held last year. HD Graphics 4000 packs 16 EUs, while the current HD Graphics 3000 features 12 EUs. However, the IGP’s frequency still couldn’t be displayed in GPU-Z and CPU-Z currently, but the core working frequency (HD Graphics 4000) was 1150MHz showed in motherboard BIOS with Core i5-3570K, 1100MHz (HD Graphics 3000) with Core i5-2500K.
As for the ordinary Ivy Bridge processors, they integrate HD Graphics 2500, the specs are not revealed, but it’s predicted to feature eight EUs, and the existing HD Graphics 2000 integrated in common Sandy Bridge processors packs six EUs.
In addition, the main change in IGP of Ivy Bridge processors is the support for DX11, while the current Sandy Bridge processors only support DX10. Moreover, its Quick Sync has been updated to the second generation, OpenCL 1.1 and independent tri-display output are supported as well.
Benchmark platform & settings
The test mainly had a comparison of IGP performance between Core i5-3570K and Core i5-2500K. The two CPU frequency was both set at 3.3GHz, they matched Z77 and Z68 motherboards, respectively. Besides, the driver we used was Intel Graphics Driver 188.8.131.5298.
Additionally we would see the gap between HD Graphics 4000 and low-end graphics (NVIDIA GT 240 GDDR3). The test platform was Core i5-3570K+Z77, and all the gamings’ resolution was set at 1280*720.
HD Graphics 4000 vs. Graphics 3000
Core i5-3570K integrated in HD Graphics 4000 outperformed Core i5-2500K by a large margin, in 3DMark Vantage Performance mode, Core i5-3570K even scored twice over the latter. In addition, in actual gamings, Core i5-3570K featured an improvement of 20% in Starcraft 2 than Core i5-2500K, and in Farcry 2 (DX10 mode), the improvement even reached 84%.
Judged from the gaming image, Core i5-3570K ran more smooth obviously in most games than Core i5-2500K, especially in Left 4 Dead 2, Street Fighter 4 and DiRT 3, while in Farcry 2, it couldn’t be described as smooth running with Core i5-3570K in spite of better displayed image than another processor.
HD Graphics 4000 vs. GT 240
Compared with last-generation products, HD Graphics 4000 really improved by a great deal in performance, however, when faced with low-end graphics card, it still had great pressure. Our tested NVIDIA GT 240 (GDDR 3) was a old low-end discrete graphics, surely it couldn’t defeat the existing new models, but it was not a difficult thing to beat integrated graphics.
If we only saw the 3DMark Vantage scoring of HD Graphics 4000, the performance was fine, which fell behind by 15% than GT 240. While in actual gamings, the gap was very obvious, HD Graphics 4000 couldn’t run smooth in Starcraft 2 and Farcry 2, it would be fine with the running of GT 240, and the frames of HD Graphics 4000 in most games was only half of GT 240.
It would be ok for HD Graphics 4000 to run some low-configuration requirement gamings, for the high requirement games, discrete graphics was needed to enjoy the gaming-play.
Lastly we posted the 3DMark 11 scoring of Core i5-3570, Ivy Bridge processors all supported DX11, but support and smooth-running weren’t the same thing, in 3DMark 11 Entry Preset the processor only scored 1478, very often the frames featured just single digit, which was far away from smooth running.
Compared with last-generation HD Graphics 3000, HD Graphics 4000 integrated in Core i5-3570K outperformed the former by a large margin, which came along with smooth gaming running experience. It would be fine to play some low-profile requirement DX9 gamings (such as Left 4 Dead 2, Street Fighter 4, etc), but for some high-demanding DX10/DX11 gamings, it would be reluctant. HD Graphics 4000 still featured some gap with low-end graphics cards, and therefore, it’s suggested to get a discrete graphics card with decent performance if you would like to fully enjoy the games.
According to the current performance, HD Graphics 4000 can’t beat the APU integrated in AMD A8 series, maybe its performance is close to that in AMD A6 series. Would you like to get more test on Ivy Bridge processors? Just stay tuned!
