Are Intel’s CPU-integrated GPUs Good Enough for CAD? (Part 2)

Last week, I talked about why Intel’s latest generations of graphics-enabled CPUs might make CAD professionals think twice about paying extra dollars for a discrete graphics card on their next workstations.

As I mentioned previously, the low-cost Entry 3D segment has seen steady gains over the years, for a logical reason … as average street prices fall and capabilities climb, the Entry class satisfies more and more of the workstation community. But then right around the start of 2011 — precisely when Sandy Bridge comes out of the chute in workstations like HP’s Z210 —Entry 3D shipments start to flatten and then decline (albeit modestly).

Why are Entry 3D sales more indicative than other segments of a possible erosion from integrated Sandy Bridge graphics? Well, if recent buyers were to opt for Sandy Bridge graphics, the discrete card they’d most likely be opting against would be an entry-class product. Those shopping for a mid-range or better card aren’t going to be enticed by CPU-integrated graphics. Such buyers have both the need for performance and the dollars to pay for it. So if Intel’s new push into professional-brand integrated graphics were to have an impact, we would logically see the effects first in Entry 3D. And that appears precisely to be the case, albeit at a far-from-dramatic rate.

Don’t expect the impact of CPU-integrated graphics to be either dramatic or fast-paced. For the near term, while Intel’s “good enough” graphics performance can satisfy a big chunk of the mainstream, it will be an appropriate choice for only the most budget-conscious professionals. Still, the trend line, as it was in mainstream graphics, is pointing just one way: up. Sandy Bridge’s successor, Ivy Bridge, has just recently begun shipping in the market, and it again provides a substantial bump in performance and features over its predecessor.

Give it time, and integrated solutions will eventually hold significant share among CAD pros … not to the extent it does in mainstream PC markets, but significant share nonetheless.
