DDR4 + AMD APU

[hotpocket800]

Alright, so i just had a moment. I go on pcpartpicker and wasnt expecting ddr4 to be so cheap and with speeds up to and exceeding 3000mhz.Then it hit me. What if amd releases new apus that can use this?

 

Ive seen plenty of tests that show how memory speed is one of the bottlenecks for this technology because all gpus use really fast ram to an advantage.

 

Of course it wont be dedicated gpu good, but that could be really exciting to how fast these apus can get.

 

What do you guys think?

[scobie56]

i dont think any amd cpu supports ddr4 atm 

[PlayStation 2]

it would definitely benefit from it if it has the capability to do so

[airdeano]

that'll possibly happen on the Zen platform.

[PHInfinite]

They are in zen.

Well I didn't know pcpartpicker had a section for totalitarian countries

DDR4 is barely any faster than DDR3 altough the advertised clockspeeds sounds impressive the exeptionaly high CAS latency on these sticks make the performance gains in overall performance and bandwidth negligeable at best.

They are in zen.

I didn't know AMD would also release new APUs with ZEN.

Idk but I'm sure they are.

They're going to be the main focus of Zen from what I've heard.

...

 

I did bandwidth tests and my Ripjaws 4 kit at 3000mhz CL14 is double the bandwidth of my old DDR3 kit.

yeah...sure!

 

3000/14= 214.28

1866/9=207.33

 

= 3% more throughput. WOW!

[hotpocket800]

well, we'll just have to wait and see

[Senzelian]

I did a little Google search and found some stuff about it.

Yup, you are right, it's actually an APU.

[Gofspar]

yeah...sure!

Wheres your X99 rig to prove this?

also, these are maths they don't need to be proved they are cold hard undeniable facts...

[Nena Trinity]

Zen so I guess late 2016?

[Helio_Vice]

No, the design is going to be APU but to also completely redesign their Desktop CPU line.

 

Reports from AMD indicate that Zen will abandon modular CMT (Clustered Multithread) for a SMT (Simultaneous Multithreading) microarchitecture, the model Intel uses. Adapting their chips from the less-popular CMT to SMT. Reportedly, the Zen architecture will be built on a more efficient 14 nanometer process, rather than the 32 nm and 28 nm processes of previous AMD FX CPUs and AMD APUs, respectively. It will feature a unified AM4 socket with its GPU-equipped APU counterparts,^[11] and feature DDR4 support and 95 W TDP.

You know how new DDR4 is compared to 3, right? Those are early numbers. Don't throw a link and call it cold facts. I would like to see citation of this 100% bandwidth increase, however, @Gofspar

Fair enough, here is skylake recent matchup DDR3 vs DDR4...enjoy!

Thank you, I'm behind on my research lately, usually I'm up to par.

For these tests...Memory speeds were DDR4-2133 C15 and DDR3-1866 C9 respectively.

 

...and as you can see both perform about the same, within margin of error...DDR3 beating DDR4 in about half the tests...and this is only 1866mhz CL9...

you know as well as i do that some premium DDR3 kits can easily run 2600mhz CAS10...so yeah.

ZEN APUs will use DDR4, but those APUs are a good 12-18 months away AT LEAST
