Fallout 3 Game Performance
Bethesda’s latest game uses an updated version of the Gamebryo engine (Oblivion). This benchmark takes place immediately outside Vault 101. The character walks away from the vault through the Springvale ruins. The benchmark is measured manually using FRAPS.
For the price, the gaming performance of these chips is pretty good. The Core i3 540 and 530 are competitive with their similarly priced AMD alternatives.
Left 4 Dead
More of the same. At $133 or less, the Core i3s are good gaming chips - especially when you consider how far you can overclock them. The i5 661 doesn't make a whole lot of sense though.
Far Cry 2 Multithreaded Game Performance
Far Cry 2 ships with the most impressive benchmark tool we’ve ever seen in a PC game. Part of this is due to the fact that Ubisoft actually tapped a number of hardware sites (AnandTech included) from around the world to aid in the planning for the benchmark.
For our purposes we ran the CPU benchmark included in the latest patch:
In games that are better threaded, the old Core 2 Quad Q9400 is a better buy. But you do get more balanced performance out of the new i3s. Compared to the Athlon II X4 these new chips make sense.
Crysis Warhead
Crysis also shows the Clarkdales in a good light: we become mostly GPU limited, and the i3 parts do very well against the AMD Athlon II chips.

On page 13, in WoW benchmark, the Core i5 750 outperforms the Core i7 870 by more than 30% (92.3 fps vs 70.6 fps). Anything wrong here?Crimson67 - Tuesday, January 5, 2010 - link
WoW doesn't seem to like hyperthreading, it's the only explanationereavis - Wednesday, January 6, 2010 - link
is it using the hyperthread core on the 870 but a true core on the 750? That would certainly slow it down. If it's using a true core on both it should be better still.Dyzios - Monday, January 4, 2010 - link
Remember NVIDIA Hybrid idea, to have two GPUs ? - one weak for 2D/light 3D graphics and powerful discrete GPU for gaming? Those CPU makes sense for this approach - however Radeon 5870 also has good point with optimized low idle power consumption. Maybe still there is point as even Radeon cannot go very low as GPU on-die. The only question is to have capability to switch HDMI output between on-die GPU and discrete.I wonder how this works currently - still needed to stick to DVI output from Radeon or can be combined?Zool - Tuesday, January 5, 2010 - link
If the 40nm 5600 series cards will show the same improvments in power usage than the 5800 series than u can forget the intels GMA graphic.I think that for a 2D card/3D discret card u can buy a mobo with a dirty cheap intel GMA on it clocked much lower if u realy need.

The graphics comparison isn't exactly fair but in the end, it's not something AMD should be too worried about. The i5-661, with its 900MHz 45nm GPU, is being compared to the old 790GX's HD 3300 which operates at 700MHz on a 55nm process. I admit, in the benchmarks we're talking the best i5 vs. the best AMD has to offer, but considering...a) the relative performance of the i5-750 as compared to the PII X4 965 which is usually manifested as an advantage
b) the fact that the 32nm i5s can increase their core speed by 133MHz and 266MHz thanks to Turbo depending on the number of active cores
c) most games still aren't designed to take full advantage of multithreading so four cores may not yield a tangible performance increase
...then AMD's still in the lead for IGPs. If the 3300 had been clocked at 900MHz, would it have lost even one of the listed benchmarks? I'm not sure it would have. What's more, we're still talking a 55nm part; we all know of TSMC's issues with the 40nm process and AMD going fablress, so is it unreasonable to expect that AMD could move their IGP production en masse to 40nm with TSMC or 45nm with GlobalFoundries?
In closing, it's a big step forward for Intel, however if AMD came out with a higher clocked 40/45nm IGP then, Sideport or not, new tech or not, AMD would be far ahead, at least on gaming terms. Sideport does very little for the performance of current AMD IGPs, anyway.
I just wish AMD were able to release a Clarkdale competitor sooner rather than later.

the IGP on Clarkdale isn't maxed out at 900Mhz; It too can be overclocked significantly. Here's an article on techgage showing an OC to 1133, for example.Remember that Intel is very conservative on binning parts to ensure no issues with reliability over time (compare vs nvidia mobile gpus).

Maybe so, however a 40/45nm AMD part could reach similar clockspeeds. I just don't think that, clock for clock, the new Intel IGP on the Clarkdale die is as powerful as anything AMD or nVidia can produce on the same scale. It's a good step forwards, just not the leadership that some may have been expecting.silverblue - Wednesday, January 6, 2010 - link
Slight mistake... second best 32nm i5 that Intel has to offer. However, I doubt the performance increase over the 661 will be very noticable with the IGP; won't it be clocked the same in both?Zool - Monday, January 4, 2010 - link
The irony is the biggest drawback of these cpu-s is the 45nm intel graphic on other die with the memmory controler. The die savings from 45nm vs 32nm are quite big.If they would make just 32nm dual core nehalem with memory controler on die it would be still much smaller(and only litle bigger than the clarkdale without imc) than the GMA die with memmory controler.
The whole thing would be solved with everything as one on 32nm.
I think plenty of people just wait for 32nm quad core nehalems without the useless GMA graphic.
Actualy what is the cost of dirty cheap GMA in penryn based 3 package boards. Like 5-10 dolars ?
