New GPUs will highlight Intel's 22 nm fourth-gen Core chips

As Intel Corp. (INTCwinds up towards the launch of Haswell Intel's 22 nm node architecture refresh and designated CPU core for fourth-generation Core i-Series processors, it's spilling details on the chips' graphics processing unit.  Haswell cores will be paired with three different tiers of GPUs, depending on the power envelope.

I. Enter a New GPU Brand

The top two tiers of the on-die GPU lineup introduce Intel's first ever branded GPU lineup.  Advanced Micro Devices, Inc. (AMD) has Radeon, NVIDIA Corp. (NVDA) has GeForce, now Intel has announced it will call its high end GPUs "Iris".  In the past it relied on humble numbered die-parts with no separate branding (e.g. last generation's Intel HD 2500 and Intel HD 5000).

Intel had briefly toyed with the idea of releasing Larrabee-branded computation-heavy discrete GPUs.  Ultimately Intel abandoned that project choosing to stick on an embedded path, which took it to Iris.

The new GPUs have been referred to as GT3 in past roadmaps (and shown running Skyrim in demoes).  All of the new chips will pack support for OpenGL 4.0 and DirectX 11.1.

On the lowest end power-wise, Intel's 15 watt Haswell chips (like the one presumably powering the company's 17 mm-thick hybrid ultrabook reference design) will get the HD 5000, a mild upgrade.  The performance increase in this segment is expected to be around 50 percent (over the HD 2500).

AMD's Fusion efforts were ultimately a wakeup call to Intel on the value of a high-quality embeddded GPU.  But it appears that the student has now become the master; the performance of Iris and Iris Pro come closer to matching a discrete GPU than AMD's Fusion chips have thus far.

II. Discrete Graphics Performance in an Embedded Package

Things will start to heat up in the U-Series (like Core i5 branded) 28W mobile CPUs, which will get the new "Iris" branded GPU unit (the full name is Intel Iris HD 5100).  It's roughly 2x faster than the HD 4000.

The Iris Pro gets a special boost -- new dedicated EDRAM (embedded dynamic random access memory) is also now for the first time included with the GPU part of the die.  On high-end laptop chips -- the Core i7 branded H-series of mobile chips (47-55W of typical power) -- this is expected to again represent about a 2x speedup.
 
Intel Iris Pro

On the desktop side, Intel's GT3e "Iris Pro" part will get an even bigger boost, reaching a 3x speedup in the R-Series (65-84W) desktop chips.  The M-series laptop and K-Series desktop chips are expected to also have access to Iris Pro, although Intel hasn't revealed their exact level of performance increase.

An Ivy Bridge i7-3770K part scored around 1560 in 3DMark 2011 [source], thus the new Iris Pro-equipped chips should be scoring over 3000, if Intel's performance claims are accurate.  That indicates that the Intel's on-die graphics will be slightly better than a full discrete AMD Radeon HD 7750 GPU which scores around 2900 [source].

Whether the real-world performance truly lives up to that remains to be seen, but it's clear that this is Intel's most powerful GPU ever, and worthy of its first-ever branding.

My CPUs are at 100% all the time. (Or at least they were. I'm taking a break from distributed computing projects at the moment.) There are still applications that will never have enough power, like DC projects that simulate protein folding, find prime numbers, crack encrypted messages, or search for extraterrestrial life. Chess engines will never fail to benefit from being able to search more moves per second.

But yes, there is no need for more power to do most of what we do now. As I pointed out above, when more power became available, new technologies came along to take advantage of it. What would we do if we suddenly had 10 or 100 GHz CPUs? I don't know, but someone would find a use for it, and it might forever change the way we use computers. If you build it, they will come.

LOL... True, but the thing about distributed computing is you are basically giving out your idle/spare CPU processing power to whatever cause... It works because there SOOOOOO much free CPU power already. OTher than that and a few other niche things that a very small percentage of people do most CPU's on PC's are less than 5% utilized, way less.

Well...I learned the hard way about the "free" CPU power you're talking about.

This is a long time ago, mind you...but back in the day I was all about SETI@Home. I had all kinds of PCs running all the time, doing the SETI command-line client. I was in something silly like the top 0.2% of all SETI users worldwide in terms of workunits done (out of something ridiculous like a hundred million users).

Then I had a thought. And for a month, I stopped running all my PCs with SETI all the time. When my electricity bill came for that month, it was about $100 lower than it usually was.

So then I stopped running SETI XD
