Intel Clarkdale Core i5 Desktop Processor Debuts

1 thumbs up

There is little doubt that Intel's previous generation integrated graphics cores left more than a little to be desired, when it came to offloading the CPU of multimedia and gaming tasks. In fact, gaming on an Intel IGP has historically been essentially non-existent, unless Farmville is your kind of thing.

It was only recently that Intel began offering a solid HD video experience on with their G45 series chipset and even then, you needed a decent processor to help with some of the heavy lifting. However, for this iteration of integrated graphics solutions, if Intel was going to directly bolt this technology to the CPU on the same substrate, they had to beef things up a bit and indeed they have.


Intel HD Graphics Feature Breakdown

Culled from Intel's slide deck, above is a feature breakdown of what Intel is now calling "HD Graphics", the DirectX 10-class GPU core that resides on the Clarkdale CPU package itself. Intel has outfitted the GPU with 12 shader cores or execution units as they call them, in conjunction with some fairly major upgrades to the architecture. Techniques and algorithms like Hierarchical Z-Buffer and Fast Z clear have been incorporated into competitive discrete GPU solutions from AMD and NVIDIA for many years now but are just making their way into Intel's IGP (Integrated Graphics Processor) solutions. Specifically, these two features afford the GPU core more efficient operation in the rendering pipeline, allowing pixels that aren't needed to be cast out of the rendering workload early, in addition to clearing buffer memory more quickly for faster read/write operations.

      
Intel HD Graphics, On-Chip--not on Die--IGP

The GPU core clock has also been turned up to 900MHz with dynamic clock gating support or "graphics turbo" on mobile variants that, like the processor core itself, allows clock speeds to be ramped up or down based on workload. Finally, Intel has also added dual simultaneous HDMI output support for the platform as well.

Intel has also buffed out the feature stack as well with respect to HD video processing, now offering dual video decode for picture-in-picture TV tuners and other applications and higher 12-bit per component color depth in support of the full HDMI 1.3 specification. DisplayPort support has also been dropped in, in addition to Dolby TrueHD and DTS-HD audio.

   
A Closer Look At Intel's New HD Graphics Control Panel

All told the enhancements to the graphics and media capabilities of Intel's HD Graphics solution are significant and bring a very much welcomed new level of functionality to the solution that previously Intel simply didn't compete well in versus competitive IGPs on the market. Intel's capabilities have vastly improved in this area. And of course, we'll also chart out some of the hard benchmark data for you on this, in the pages ahead.

     How are these on a heat dissipation scale. I know in general GPU's run hotter than CPU's when in use, in many cases considerably so especially when built on a 45nm or larger scale. The GPU on these chips are therefore (at the 45nm spectrum) considerably larger and use more power thereby producing this higher heat level. I also notice on these units they are quite close together leading to heat bleed inside a package, or at least I would fear. I also noticed you overclocked it which would lead to even more heat. In general heat is bad in a case like this component build I would think it to be quite high on anything over stock, and even at stock. I was thinking about this the other day while thinking about another issue. The first group who buys in many cases are the enthusiasts. The enthusiasts also generally want more for there money, and therefore in many cases will OC.  Therefore it would actually be in a companies interest to release unlocked high end components. Then a good amount of those who buy them will OC(overclock) them and the component lifespan would then be shortened. This would seem to be a varying point, but in any way across the board would occur to some point. The consumer who does this will also almost always turn around and buy a new on as well as components to go with it (MB,Ram,GPU etc), thereby feeding the market. So you look at the enthusiast market which is generally called a small sector of said hardware market, but if because of things such as this they buy double the amount of hardware in half the time of a normal user they purchase 4 times what a general user does. So is that market sector really small? Anyway with these thoughts regarding unlocked CPU's and or other components would such heat issues not least to a greater turnaround rate for the market in general or Intel at least with a component like this on a much broader spectrum and doubly (or 8 times if they already purchase at a 4 times greater frequency)  with the enthusiast market.

This doesn't seem to be the solution if you're an Extreme Gamer kind of guy. I wouldn't consider it for such use anyway,....It's more like a mainstream setup and with proper cooling should do what they say it will over the life expectancy of the unit. A real high end CPU and the GPU of your choice is the way to go for OC'ing madness. I just can't see the merging of CPU and GPU as being groundbreaking in any way other than the technical aspects of actually doing such a thing.

I'm stuck on the Idea that they remain separate and be interchangeable separately.

Again, this would be the processor you buy for Mom's Pogo games and e-mail fun.

yeah that's true I was just talking about the heat of this unit contained in such a small space. with both a cpu and gpu in one package it has to cut into the life span of such a component it would seem to me.

Well, they run cool, so I wouldn't be concerned with the additional heat of the GPU affecting the lifespan.

Also keep in mind, it's not a single die. As long as a proper heatsink is used, heat will be dissipated without an issue.

Embedded solutions will benefit from integration in the future.

I wonder how the GPU is going to do. Seems like a strong CPU with a weak GPU. Good for office work, and grandma. I think AMD's fusion will be more balanced, and a better deal for most people that want to do more that use office and browse the web.

I really agree with this. I don't think these are aimed at us at all. I think they are more for Dell and will help Intel keep that IGP market theirs.

I doubt that this is really geared for the "High-End gamer".

This however, will really be step up from the more business related desktop machines. A lot of the Dell systems that I see at work host the "Intel(R) G33/G31 Express Chipset Family", and that is on the better, newer side of the the "fence". Some programs, require a bit more video to run properly and some clients don't want to see video card upgrades in their budget. Not for Office machines anyways. This solution will help alleviate some of these issues at hand.

Also you have to think of the "Lite Gamer" Intel integrated video won't run a whole lot, this will help them with some of their problems as well.

And last but not least, the whole HD everything kick. Blue-ray Dvd drives/burners are really becoming a more common place as their prices have been steadily dropping. This will be Intels "marketing-intro", if you will, to keep up with this technology as well.

I am of course referring to "Cookie Cutter systems" such as Dell, Hp, Acer, and the like.

Considering the price and what you can get instead of one of these things, they really serve no purpose.  Lets take a $200 cpu and stick a crappy $5 gpu on chip.  Now lets sell it for $300!  These integrated i5's are not worth it in the slightest, more along the lines of an "Us First!" before AMD's Fusion comes out.

Now the i3's at $100~133 are a much better deal if you don't need anything past integrated graphics.
