The Intel Core i3 530 Review - Great for Overclockers & Gamers

Integrated Graphics - Slower than AMD, Still Perfect for an HTPC
Intel was very careful to seed reviewers with the Core i5 661, it provides integrated graphics performance equal to if not better than the best integrated graphics from AMD and NVIDIA.
The same, unfortunately, can’t be said about the Core i3 530. With 81% of the GPU clock of the 661, the i3’s graphics are obviously slower. It’s not a huge drop, but it’s enough to be noticeable and enough to be slower than AMD:
| 1024 x 768 | Batman: AA | Call of Duty Modern Warfare 2 | Dawn of War II | Dragon Age Origins | HAWX | World of Warcraft |
| Intel Core i5 661 (HD Graphics) | 35 fps | 21.6 fps | 15.0 fps | 41.5 fps | 53 fps | 14.8 fps |
| Intel Core i3 530 (HD Graphics) | 28 fps | 17.5 fps | 9.5 fps | 34.4 fps | 45 fps | 12.5 fps |
| AMD Phenom II X4 965 (790GX) | 35 fps | 29.3 fps | 12.1 fps | 35.6 fps | 58 fps | 21.1 fps |
| Intel Core 2 Duo E8600 (GMA X4500) | 15 fps | failed | 1.4 fps | 16.8 fps | 26 fps | 11.7 fps |
The i3 does retain all of the sweet TrueHD/DTS-HD MA bitstreaming support that makes Clarkdale the perfect HTPC platform. If you don’t need the extra CPU power, the Core i3 530 could make for a great HTPC.

Bought 3-pack of win7 pro and these things run beautiful. Fast, win xp mode is supported so every app they had back with win xp still runs. I'm very happy with this platform from Intel. This was a home run in my opinion.raced295 - Friday, January 22, 2010 - link
Correct me if I'm wrong but I thought it was well understood that Intel uses processor power to accelerate gpu functions. In other words the GPU is not nearly as fast as is appears the drivers offload work to the cpu since it is very powerful. I will try to post links to support this but don't remember them off hand as I thought this was common knowledge on "in depth" sites such as this. I believe that this was going on in part on G45 at least with benchmark software. Also that the driver looks for benchmark exe's and game exe's and manipulates quality and offloads to CPU.It doesn't change much for the end user as its still faster but bottom line I don't think the GPU is as good as it appears. Net performance however is as good as it has shown and this is brilliant of Intel to do.
Submit to the community for thought.

So the integrated GPU can be overclocked really high. Nice, but we're not gaming on this thing anyway.No, what this really means is that the GPU voltage is set unnecessarily high by Intel! We'd be using these integrated GPUs to save power compared to discrete GPUs, not to waste it. It doesn't have sophisticated power management yet, but at least a reasonable voltage would be nice..

On the fourth page it says that overclocking without increasing the voltage will not increase power consumption. This is not true; while power is directly proportional to frequency, exponentially to voltage. Could you post some idle and load power figures when overclocked at 4 and even 3.3GHz? I'm always hesitant to raise the CPU voltage. Thanks.-sanders

As power consumption and efficiency has become more important, and manufacturing processes improved, how far you can push a CPU without increasing its core voltage appears to be the most efficient way to overclock. You minimize any increases in power consumption while maximizing performance.It does not say the power consumption will not increase, but that you will somewhat minimize the increase by keepingthe voltage at stock.

You're right, but one also needs to keep the absolute value of the stock voltage in mind. A fine example are the initial 45 nm Phenom II chips: reviewers applauded them for being able to OC rather high at stock voltage. However, "stock" in this case meant 1.35 - 1.40 V. That's more or equal to the maximum Intel gave it's 65 nm chips.So either one could argue "great stock voltage OC" or one could say "wasting power by setting a unnecessarily high stock voltage".

P ~ V^2, not exponential. Some leakage currents scale stronger, but these don't dominate the overall power draw (otherwise the process / design would be pretty bad).sandman1687 - Friday, January 22, 2010 - link
Sorry, meant quadratic.Finally - Friday, January 22, 2010 - link
I compared power draw under LOAD for the Phenom II 965 BE and here: http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">http://www.anandtech.com/cpuchipsets/showdoc.aspx?... you say it draws 274W (sic!), while in your database the same figure is much lower. How come?janm9 - Friday, January 22, 2010 - link
i am looking for the power consumption of the an amd athlon x4 620/605e with the 785G chipset. i can not find a review using just onboard graphics. the anandtech benchmark database is nice, but it only lists power consumption with either the 5870 or geforce 280gtx.i myself have run into problems ( artifacts ) under windows 7 with both media center and MPC-HC in 64bit with DXVA too.
thank you for writing an interesting article :)
