Adata Introduces Next-Generation of DDR4 DRAM Modules

As always when we change DDR standard it will take a few months for the new one to beat the previous generation on speed. It will be interesting to see how quickly it will be implemented.

Patiently waiting for this to hit desktops. iGPUs have been begging for it.

It's really not about a speed boost, at least not initially, DDR3 has achieved 3000Mhz at 1.65V. So a DDR3 module at 3000Mhz and 1.65v will be faster than these 2133Mhz 1.2v DDR4 modules unless there are more channels for DDR4. DDR4 is about power savings not speed increases. Currently 1.5v is required for 2133Mhz DDR3 I've only seen 1866Mhz using the lower voltage 1.35v DDR3 So 2133Mhz at 1.2v should give some nice power savings and less heat radiated into the case but if you are expecting all this additional speed I wouldn't get your hopes up too high. I could be wrong though maybe DDR4 will quickly scale to beyond 3000Mhz or maybe the cas latencies have improved tremendously.

Every iteration of RAM was big performance leap. It's the same right now, doubling transfer rates yet again.
This would be a very strange to adapt new memory standard just for marginal power efficiency benefit. If it's only power saving feature ddr4 is very long way from desktop.

Are you kidding me? Have you followed any DDR technology at all? On release DDR2 Was SLOWER than DDR1, DDR3 was SLOWER than DDR2 (at the same frequency) the timings are always slower! and that kills the performance. It's the same with DDR4. It won't catch up to overclocked DDR3 performance for some time. So he's exactly right, it's about efficiency and future performance scaling, that's it.
Big deal though, you can pick up 1.2V DDR3 modules anyway (not at 2133 though) but who cares a couple of watts saving.. big deal.
Will be interesting at 1500MHz (3000) otherwise.. meh. Can't believe we've been waiting years for this. We need something better than DDR technology already.

Here's an interesting read for ya.

Why compare overclocked DDR3 to DDR4? Most people don't overclock their DDR3 ram, so they don't care about overclocked DDR3 versus non-overclocked DDR4, aside from that, comparing over-clock versus non-overclock is not a fair comparison.

Ninjawithagun, graphics cards use GDDR5 which is based on DDR3.

Because it's at the same frequency? You are aware that high speed DDR3 RAM running at higher than 2133MHz is basically overlocked RAM right? Same went for 2133 and 1866 before they were released as a spec. By overclocked I mean everything above 2133Mhz.
