New GPUs will highlight Intel's 22 nm fourth-gen Core chips
As Intel Corp. (
towards the launch of
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
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. (
) has Radeon, NVIDIA Corp. (
) 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
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).

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.
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.
i7-3770K part scored around 1560 in 3DMark 2011 [
], 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 [
The IrisPro on-die GPU is approximately as powerful as last generation's Radeon HD 7750.

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.

I agree with you as to the PC user base.
But in the microcosm that is the gaming world there are many games, even very new ones, that are more CPU dependent than GPU.

There are very few games that are cpu bound and of the ones that are I would claim they're poorly coded.

I'm not sure that I'd 100% go with the second thought there, but the first one is very valid.
It's a rare game that isn't GPU bound. And if it isn't, the CPU portion of the bottleneck can almost certainly be taken care of with a modest CPU - i.e. your existing CPU must really be a POS.
Virtually any gaming upgrade, if you have even a modest modern CPU, is going to center essentially all on the GPU.
