Photoshop: Future Performance: Chips and Cores, etc.

  • Question
  • Updated 8 years ago
Are you guys able to give a hint as to what facets of processors PS will best utilize in future editions?

For instance, if one is buying new hardware what should we expect to yield better results in PS CS6: clock speed or multiple cores. Is the step up to i7 chips justified?

It's confusing because looking at this page of iMac performance it looks like the i5 chips yield greater performance than the i7 "upgrade" option. One might not mind paying extra for better performance, but not for worse.

And should we expect PS and Lightroom to be moving in similar directions in this regard?

Thanks.

We already publish a couple of guides on optimizing performance with Photoshop.

But it all depends on the types of documents, tools, and commands you work with.

Generally: more memory usually helps. The tradeoff between core count and clock speed depends on the specific command. And you probably want a good GPU. Then invest in a fast hard disk for scratch, and maybe an SSD for the system and applications.

For Lightroom:

Grid searches and scrolling are most helped by having your catalog on an SSD.
Develop responsiveness is helped most by single-thread CPU speed.
Preview and export performance is related to single-thread CPU speed times the number of cores running at that speed.

Scott,

One sometimes hears speculation that moving forward PS and LR may make better use of multiple cores and hyper-threading.

I don't doubt that's true in the long run, I just wonder how true it is relative to the 3-5 year life cycle of my computers. IOW, is it worth investing in more cores and i7 chips now, or will I be onto yet another box and CS7 or 8 before that investment is relevant.

Photoshop and Lightroom already make extensive use of additional cores and hyperthreading whenever possible. And if you wait, you can always buy better hardware. Buy the best system you can now, when you actually need it.
