Haswell And 1.35 V Memory: Three DDR3 SO-DIMM Kits, Tested

Results: Adobe Creative Suite

Our single-threaded Acrobat workload sees some benefit from faster memory. The Acrobat test also gains from the Core i7-4770K's higher thermal ceiling and larger shared L3 cache.

We typically disregard performance differences of one second or less, since rounding can exacerbate tiny deltas. We don’t see a consistent trend in memory performance in After Effects; we only know that maximum memory capacity plays a big role in how long this test takes to finish.

Data rate has no discernible effect on Photoshop’s CPU-heavy filters, but faster memory does help its OpenCL-accelerated performance. The LGA 1150-based Core i7-4770K is particularly limited by memory throughput.

Our Adobe Premiere Pro workload doesn't correlate clearly to memory performance. Instead, we end up with a five-second margin of error.

    It'll be more difficult to explain why the -4770R saw so much less benefit from higher data rates than the -4770K.

    The R version has 128MB of L4 cache. At 1280x720, it is large enough for all index and vertex buffers and most textures. That is why main memory speed doesn't significantly affect Iris Pro 5200...

    Having 128MB L4 cache certainly skews things around for IGP performance, no surprise there.

    Huh, fairly surprised I didn't know about the 1.35v requirement. What happens if you pop in 1.5v in there? Is this just a power savings thing or did intel really mess with their memory controller for laptops?

    i wonder how those 1866 would do on a newish amd apus 6800k

    Wow! I know this article is about memory, but the game benchmark data for Iris Pro actually impresses me quite a bit!

    Intel really should've made socketed cpus with Iris Pro

    Tell one of these companies that makes upgrade processors to solder the 4770R on an 1150 adapter :)

    AMD must have been very envious with this Iris Pro having embedded 128MB of fast memory....which should be plenty useful for their AMD's APUs.

    intel claims that the edram costs around $80. that'd jack the a10 6800k price over $200 only to benefit the igpu (possibly the same with gddr5). imo, the weaker cpu cores wouldn't benefit much, if at all. that'd make the apus of poor value and people will argue against the apus claiming you can have a faster configuration under $200 (e.g. core i3 4110/fx6300 + radeon 7770/7750) without requiring the edram. as for core i7 4770R (and other R skus) - it's way too expensive. afaik, brix pro is barebones, the whole pc might cost near $800-1000 fully configured.

    Simply wait for Broadwell-K near the end of this year and you will get the option of buying a $300+ i5 or $400+ i7 with 128MB L4 cache and Iris Pro.

    From what little info leaked about it so far, it is still unclear whether or not there will be an option to buy a desktop Broadwell without that ~$100 extra.
