Thoughts on AMD Radeon R9 M370X over the Nvidia 750m?

Has anyone noticed this in Apple's spec for the R9 M370X:

Support for up to 5120 by 2160 resolution at 60Hz on a single external display (model with AMD Radeon R9 M370X only)

This is higher than what's possible over DisplayPort 1.2 (4096 x 2160). Could the R9 M370X be the first graphics chip on the planet that supports DisplayPort 1.3? DP 1.3 maxes out at 5120 x 2880, so this is not quite there. Wonder what's going on there... maybe it's a typo on Apple's part, or maybe Apple is fudging the DP 1.2 spec to support a future 5120 x 2160 panel they're planning?
 
Whats up with the max supported resolution of 5120x2160 for the M370X? Does this mean that the new card has Displayport 1.3? There aren't any other GPUs that can do that. But if it is, why can't it do full 5k (5120x2880)?

Also, I'll ask the same question as everyone else, does anyone know which AMD chip design is in this? Tonga? Fiji? Something else?

Just posted this question up above–– 5120x2160 over a single cable would imply either that the R9 M370X is the first GPU on the planet to support DP 1.3 OR Apple is fudging the DP 1.2 specifications to support some type of product they have in the pipeline. They worked with AMD to do this for DP 1.2 and the 5K iMac.

5K Thunderbolt display announcement at WWDC next month?
 
what about gamig performance nvidia always did a better job releasing drivers to increase the performance of games...
i have mid-2014 mbpr with GT750M and i can play cod AWon High and battlefield 4 on mediom both full HD resolution i wanna see if this is worth the upgrade and my macbook pro has graphic switching problem that is bothering me too ...(still inder warranty)

Basically what I want the know too.
 
personally i think its not worth the upgrade pay 2500 just to raise gaming and video editing experience and nothing innovative more than force touch which is in my opinion something ridiciulous and that extra hour of battery life doesnt make it superior to mid-2014 model may be for 2012 or pre-retina users its a decent upgrade...

If they update the Mac Pro's with some new GPUs in AMD's pipeline that may have DP 1.3 at WWDC then I could see this happening. Otherwise it seems unlikely that Apple would release a display that only a subset of brand new 15 inch rMBPs could support.

I think what's more likely is abandonment of thunderbolt and a return to displayport for their next display. This way the new MacBooks could eventually support them when Skylake or later adds DP 1.3 support. This may even come in the form of a USB-C sink on the displayside.

My guess is that we'll see an entire refresh cycle before we get the new displays. New Mac Pros, MacBook Pros, and MacBooks all with USB-C and DP 1.3 (all happening by mid-2016). Once this happens, it'll be a single USB-C cable from the display to simultaneously charge the notebook and drive the display.

That would be a serious downgrade as it would lose all the hub functionality and just be a display. Doubt it.

Nope, it would not loose hub functionality. USB-C carries USB 3.0, 2.0, Displayport, and 100W of power all over a single cable. Thunderbolt does the same, but with even less power capabilities than USB-C. I personally think that thunderbolt is a cooler piece of technology because you can run any PCI-E accessory (GPUs, TV tuners, sound cards, you name it!) over that interface. HOWEVER, I think apple has signaled their vision as USB-C as the future.

No 5k video output on the German Apple Store site.
Maybe premature information? Is 5k coming with Skylake?

As I am in that group (2010), I'm considering it (and I'd just take the depreciation hit and buy a Skylake a couple months after they come out so any potential issues may be resolved).
 
Lets all take this time to start a new rumor. Clearly 5120x2160 is the resolution of the yet to be released apple display, which would be a retina 2560x1080 ultra wide display. Lets take a guess and say it will be 29 inches. Boom! New rumor!
 
It must be faster than 640 GCN core GPUs, but must be slower than 2048 GCN core one. Possibly its also cut down Tonga chip.


Its completely new silicon from AMD with DP1.3. I don't see a possibility to fiddle with DP1.2 spec, and push 5K through it when it struggles sometimes to push 4K displays.

Yeah I would also suspect something new. However, AMD helped them do it for the 5K iMac... however that required another display controller... which maybe could also exist in a new cinema display??

Anyways, yeah, let's all start the widescreen 5120 x 2160 5K wide-screen rumor.

While Skylake would bring 5K to all of Apple's offerings with integrated graphics, it's possible to imagine that 5K support could come earlier through AMD's discrete GPU offerings in the iMac, Macbook Pro 15 inch, and Mac Pro.

Does anyone know historically what Apple has done with this? Back when the the LED Cinema Display came out it just supported DisplayPort... how many of Apple's current offerings were still on DVI output only?
 
Its single signal for 5K. And it goes at 60Hz.

It must be DP 1.3.

Also, Im pretty certain that we will not only see Retina 5K Thunderbolt Display, but also Retina 4K Thunderbol Display. Just 24 inch. And that will the form that will iMac morph into.

Base one with 1.4 GHz CPU will still be 21.5 if anyone would ask me for opinion.
 
370X seems to have specs like M275/M265X and that does not bode well. They deliver just a little over half the 960M performance. So they beat a 750M but not by much.
What is Apple playing at? Why not just drop the dGPU?

It should be a M265X with probably higher clocks. So maybe 30% faster if we are optimistic.

You can get a Asus G501 or UX501 for 1500 which is a lot less, with much better performance. Seems doubtful I will get a Mac again when I update mine.

The only confusing thing for me is why is it listed as 5120 x 2160 instead of 5120 x 2880, which is the full DP 1.3 spec.

And yes, I think it would be awesome if they released a retina 4K @ 24 inch and a retina 5K @ 27 or 28 inch. However, I think thunderbolt is still up in the air... why sell a display that won't work the entire product line... including the brand new MacBook, especially if USB-C can provide the functionality that most users need.

If this GPU includes DisplayPort 1.3 that would be huge and a very good reason for them to pick this up. It would assure that this computer works with whatever 5K display they have hidden away for the future.

How can you even compare an osx device to those losers?

Every windows device halts in 2 years, while mac os lives on, even the comparison is proof enough that you know nothing

If you want gaming performance, buy the cheapest windows device that fits your requirements, play games on it, re-format when it halts, or just dump it like everyone does, let mother nature take the hit

It may be the GPU limit, not the connection.

Its not rebrand of M265 or M270. Its much robust GPU. If it would be that, it would not be faster in T-Rex Offscreen test, than M270X, that has been linked here in this thread already.

I hope you ommited the ^^ by accident.

I just checked prices. I don't know if anybody in my country still buys those notebooks. 2800€ for the dGPU model. I payed 2300€ for mine in 2013.
$ version without VAT 2500$ EUR/USD 1.115 vs 1500$ of the Asus
The Asus has the better screen a non jerky operating system that actually performs well and works for every use not just work and cost A LOT less.
I like OSX mostly but it ain't worth this.
