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.

so if a CPU from 2006 is still competitive, between the decline in PC sales, the lack of competition for the performance crown, and the threats to Moore's Law posed by the laws of physics and Moore's Second Law (aka Rock's Law), will there ever be a desktop CPU that can render an i7 3770 obsolete?


Pretty much the cpu world has become pretty yawn worthy. All of the current excitement and big improvements are in phone and tablet computing. It still takes a ridiculous amount of money in graphics cards to max out my core i5 Sandy Bridge.

Why are you complaining that the 2012 300$-CPU only outperforms your 2007 (Core 2 Quad wasn't even released in 2006) by 40% in one specific, badly optimized software? I mean, first of, the 3770K outperforms a Q6600 by an easy 100% in most benchmark tasks, see http://www.anandtech.com/bench/Product/53?vs=551 .
Second of all, you should compare the 1k$-Release CPUs from both years, thus http://www.anandtech.com/bench/Product/53?vs=551 with a 200% performance boost in Multithreaded applications.

And sure, the Q6600 outperformed a P3 600MHz from the year 2000 by a factor of 25 instead of the factor of 3 you got now, but it also incread the TDP by a factor of 6 to 7.

Oh, and here is a tip: If you do not care about the GPU part, don't buy it. You could have gotten the CPU-Performance of the 3770K without the GPU-part as a Xeon 1230v2, for 2/3rds of the price-tag.

Sorry, the 2nd link should have been different from the first one of course:
