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.

Exactly... Even nerds like me stopped. I upgraded my PC's on average probably every 6 months since the Pentium 1 was out. Like an obsession, wasting countless dollars on it... But even I stopped at Sandy Bridge. I put it in 2 years ago, skipped Ivy Bridge and am skipping Haswell as well. There just isnt anything I do that needs more than a quad core i5 Sandy Bridge. That will run any game and pretty much anything else I can think of at amazing speeds. There just isnt a compelling reason to upgrade, even for the techies.

Yup, I'm pretty much in the same boat.

Core i5 SB is just an outstanding performer.

corei5, specially if you have an unlocked one.. is a godsend..
need a bit more perf? just overclock it a bit more!.

What are the chances that you were in your teens or twenties when you were doing major PC upgrading and now because you're in your 30's or 40's, married and have kids you don't time to do it anymore.

No, I'm not describing my life. ;)

Actually, I am.

Similar to me too. :)

I stopped years ago with an OC'd Q6600 G0. Several years later and all it really needed was an OC bump (now at 3.0GHz), an SSD, and GPU upgrades (now running tri-SLI with PPU). Well, there's a Core i5 2537M in my Alienware notebook, but both systems could use better graphics these days.

I'll admit: I do a lot of my encoding stuff on my twin brother's i7 system. :P

I fell that I've been waiting for that '50% better' improvement in CPU processing power before I open my wallet and I get disappointed after each announcement shows a 15% improvement with a large focus on on-die graphical prowess.

Phenom II to Bulldozer wasn't great. Bulldozer to Piledriver wasn't great. Sandy Bridge to Ivy Bridge wasn't great. Ivy Bridge to Haswell is showing a 15% improvement in CPU, so not great.

Yes, I know on-die GPU is the focus and that's showing massive improvements. I personally won't be interested until they negate the ~$150 [7790] graphic card segment (they're already encroaching on the ~$50 [7730] to maybe $100 [7750]) as then I'll maybe consider not buying a graphics card. I know that we have to go through this pain to get there but I feel that we've worn this pain for over 2 years and don't, as the fun passionate consumers we are, deserve another 2 years of 15% CPU improvements.

Yeah my gaming rig is an i5 2500k running at a modest 4.2GHz with 8GB of RAM currently and a 7950. It's already almost a year old and I expect it to last me another 2-3 years at least.

Some people complain about consoles holding back PC gaming. Honestly I've stopped caring about the graphics so much and just want quality titles with a plot and good gameplay. So I care more about that. Console gaming holding games back a bit on the graphics department has saved me the money of constant system upgrades that were kind of necessary nearly every year or two in the early to mid 2000s.

The problem is that while the graphics are dumbed down for consoles, so are the story and plot lines. Console titles have always been more flash than substance and have shown that people are willing to buy the same thing year after year and year with just minor tweaks, so why bother making a quality title.
