A 4870 can't run Battlefield 4 because it can't run Direct X 11.

Yes it can. BF4 can run even on the 8800GT. DX11 API can target both DX10/10.1 and DX11 hardware.



If Mantle can make a R9 290x and Core 2 Quad or Phenom II X4 run BF4 without bottlenecking, I'll be sold.

Why are so many pushing Mantle as the best thing since 3d? Its a bunch of hype made to try to sell GCN hardware. We have no real data just a bunch of hot air. Can we not reserve our extremely strong convictions until there is at least something on the market to go on?

What's it to you if some want to speculate based on information to hand?

Whats it to me? I have been reading that mantle is the best thing ever without an ounce of proof. That nvidia and intel are completely doomed. Call me a realist i guess cause i believe that some bold claims would need at least something to back it up. I have outlned my case and no one adressed it n a proper manner. You cant say just say mantle will work for everything as it is a down to the metal api aimed at very specific hw. Once you start adding more compadibility it will not be so close to the metal anymore.
.
Its a very short term project to try to gain a leg up on their compeditors. Once gcn is gone, so is mantle

mantle isn't to the metal as we first thought, it is a thin layer!!!!!! you don't need GCN for mantle...

I addressed your points, just because you didn't like it doesn't mean it wasn't done in a proper manner. However, let me do it again, point at a time.

Anyway, i keep hearing that Mantle is so easy to code for but where is the BF4 mantle version?
They always said 8 weeks. It's been 5 weeks. It's coming, soon.

There are some big issues i see with mantle that no one wants to address, Of course there are more efficient ways to render but you have to ask yourself why the market shifted towards Direct X in the first place. Simple, compatibility. Mantle does not solve this major hurdle. Its a huge deal.
The market shifted towards DX because the time suited it, and Microsoft carried a huge amount of weight and really cared about desktop back then. The issues that plague games today didn't exist nearly so much then.

You can buy games today on PC that run on a 9800gtx or an HD4870. You can buy a game 5 years old and still enjoy it on a gtx770 or 280x.
The problem is Mantle introduces more problems than it solves. It is not a solution but an attempt to get a leg up on the competition. It is a short term ploy. It segments and isolates. You cannot have a huge variation of HW with mantle. Its GCN only. What is PC gaming if it is not a huge variation of HW and configurations? This is not a solution but an attempt to push everyone to buy a console wannabe PC with AMD APUs and GCN graphic cards. Why would i want that? When I could just buy a PS4?
The problem you're having here is that it's not actually about *you*. It's about what the game devs want. They all want Mantle instead of DX. DX, GL and everything else would already be dead if Mantle was multi vendor - that's how much more advanced it is.

When 80% of the PC market use something other than AMD graphics-When 80% of the PC market use something other than AMD CPUs, I just dont see how anyone really expects Mantle to change anything. It will get about as far as AMD can fund it. Thats about it. However many games AMD pays to be ported to Mantle will be ported. It is extra work and it will only benefit GCN cards. It will never take over, it simply cannot. It is not capable. You need something more like DX to have compatibility over a huge variation of HW.
Already answered. AMD can easily afford to pay for Mantle compatibility for every single top-100 studio game released this year, if they had to. It's really not that much money in the grand scheme of things.

No one in their right mind would build (NEW) product today exclusively on DirectX or any vendor locked product. With OGL running on Mac/Linux/Windows/iOS(es)/Android(es), it's a no brainer to put your support there. We just need more companies like id software that put their muscle behind it.
I'm programming my own game now, and completely ignoring DX support. What advantage does it give me if I can get acceptable performance out of OGL? Nothing, just another target that has to work correctly. I want my game to run on your Mac, your Windows machine, and your Ubuntu machine. Don't you?

If I were Valve, I would simply start supporting OGL-only on my own games. Force AMD/NV/Intel to support it better on Windows in their drivers- helps get the ball rolling for SteamOS as well.
That said, if I were Valve or DICE, I'd welcome Mantle if the performance advantages were useful needed. It's apparent they were, if devs are asking for lower level APIs like Mantle. AMD is just the company in the best position for such a thing, and no one else is. I'm definitely more interested in picking up AMD hardware across the board going forward, namely HSA class APUs and onward.

Crypto Mining could destroy AMD's Mantle and Gaming Entrepreneurs if the General Public can not get their hands on a R9 290/X within the released price range promised by AMD.

Since I'm obviously the prime 'culprit' here, how about you quote one or more specific points from one of my posts and refute specific points with specific counterpoints?

Tossing off undifferentiated, unsubstantiated gloop like "That nvidia and intel are completely doomed" doesn't hack it.

or after the mining craze, the second hand market would be flooded with cheaper 2nd hand gfx cards.

Actually, Mantle is not tied specifically to GCN. It's been reported many times that all the GPU has to do is support the minimum Mantle feature set.

One does not need to refute any of your claims. You are the one making all the claims about what mantle will do. The burden of proof lies on you to provide independent data to back up these claims. The simple fact is that it is impossible to do so because there is not one commercially available game out yet that supports mantle.

True, but apparently GCN is the only architecture currently supporting the minimum Mantle feature set.

It certainly will be good for AMD to be forward looking in terms of API design to make software can work with their coming architecture.

It may not be the best thing and if it was just AMD touting it may be just PR wind with empty claims but considering Repi was very vocal for years and one of the most respected developers on the planet -- carries a ton of weight to me -- coupled with more developer momentum -- holds potential and promise!

The key for me is its efficiency -- looking forward to it and great to see excitement for the AMD and Radeon brands. Bold move and hopefully AMD is rewarded for it!

Just to point out even if it were just AMD, that wouldn't make it "just PR wind with empty claims" in general terms and when communicated as part of a public presentation with accompanying slides in particular terms - there are legal considerations - the wording on such slides are carefully chosen and vetted.

Also the fact it's AMD, a corporate culture, is known for being relatively straight talking, not Nvidia, an infamously personality/ego driven culture notably not known for it's straight talking ways.

Some people have argued that theres no way out of this for Nvidia, not with steam box, not with creating their own API(as AMD have such a hold in the console market) and theres no way they catch up on performance with Direct X.

So what if Nvidia designed a massively multicore processor deisgned for feeding the mantle API, and designed to dominate in games, rather than compete with intel for general purpose performance.

I would like to watch Nvidia build a similar API for its cards, and watch all the Nvidia fans jump on board and argue why its going to be so good. Thats all it boils down to, the fact that many people have spent a lot of money buying an Nvidia card, and are worried they could become relatively obsolete. So they fabricate elaborate arguments to down play mantle.
