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

Sandra's Memory Bandwidth module shows the benefits of faster data transfer, with DDR3-1866 outperforming DDR3-1333 by nearly 40%.

Sandra also demonstrates the superior latency performance of our LGA 1150-based platform compared to the embedded version, though it's unclear if the soldered-on CPU's slightly different specifications (like a smaller shared L3 cache) have an impact on timings.

The socketed platform is so much quicker that its DDR3-1600 setting significantly outpaces the embedded platform’s DDR3-1866 results, and its DDR3-1333 setting matches the embedded unit’s DDR3-1600 benchmark numbers. Since this is the same memory, does this spell doom for the embedded platform's application performance?

    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.
