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

By

When it comes to memory, most of our focus is on the desktop and its replaceable CPUs. The mobile side typically moves slower. But Intel's Haswell architecture imposes interesting changes, and we saw fit to test SO-DIMMs down at their new 1.35 V ceiling.

Results: File Compression

WinRAR, WinZip, and 7-Zip benefit greatly from fast memory when it comes to compressing files on the Core i7-4770K and -4770R.

    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.
