Has AMD had its day

From previous discussions in this forum and from pretty much everything I read Intel are clearly the best for gaming, AMD haven't been able to compete performance wise for years from what I read. I have been looking at the AMD steam roller, obviously no one can really know until it comes out, but does anyone think they will pull something out the bag, or should I just accept they have had their day and make my next build an Intel, after AMD's Bulldozer I am a little pessimistic. Also anyone heard anything new on it as I can't seem to find a news story later than august, are they still going ahead with it? I have only just heard about it so have very limited info on it
 
They've committed to steam roller (lower power usage and better instruction fetching) and then there is another for next year where they fixed some of the other stuff. The one coming out next year seems promising but the one for this year doesn't seem like it will be enough to pull them up to where they should be
 
No, it's not because they haven't cpu's as good as intel that they will die.
AMD got the same price/performance like intel, there are many people buying their cpu's.
 
I would like to see them do well with the next cpu, but wouldn't like to end up disappointed, I could have got an i5 2500k and motherboard for not much more than I spent, my previous athlon 4600+ I was happy with at the same time because at the time I think that was a pretty good processor. It will be a while before I upgrade my cpu again, but will be interesting to see who has the better cpu when it's time for an uprgade. I think I would have my money on Intel though
 
if i need cheap threads and dont care about IPC, id go amd, but if i dont care about threads and need IPC, i go intel. thats about as cut and dry as i can make it without bringing money into the picture.

I found out with my benchmark that amd isn't that bad in performance per core. Just in some aspects, in the normal integer maths it scores pretty good, but the floating point maths is really bad with amd's....
 
Regardless Smile, when I needed IPC, going from the Phenom ii 955 to this 3820, without changing graphics, the framerate for secondlife tripled, which approximately is how much quicker this chip was vs the old chip.

Yep, because everyting is a combination of this maths. But I'm looking to the price/performance. Yes, the expensive intel will be better...
 
Although i have never used an AMD chip i think ill use it for my next build (my bros build to be exact) and see for myself how good the amd chips are xD
but so far my i5 is just perfect.. Havent seen lag in a while now...
Although at 189.99 price tag of i5 i wonder if i can get a better chip from amd Since amd prices seems to be really good

I can't wait for pile driver though, really want to see how much better it is since IIRC it is getting an updated fetcher for the instructions so it can begin processing the data faster, plus it is supposed to be way more energy efficient, then for steam roller it is supposed to have a fixed cache and all.

And for what you said, IIRC, The main thing the modules shared was the floating point which is a big problem as it processes any mathematical operations greater than addition, subtraction, multiplication and division which are handled by the ALU (arithmetic logic unit). Love using my new understanding of cpu's (science fair required research and topic involves processors), although i was reading ultra simplified explanations so that might not be entirely accurate but it should at least be close.
 
I am staying with amd only until I am able to upgrade to intel cpus, dont get me wrong i really love amd and I was really hoping they would smash it with bulldozer but they didnt and they have openly admitted they are not going for the top end any longer, which is a shame as it leaves the whole game to intel, also a shame as I like how amd manage the sockets on their cpus, eg am3+ working with am3 cpus, intels constant change is annoying but I know that if I went for and lga 1155 board with I5 which does well I could move to an I7 in the future wheras with and am3+ board sure I could stick with my current atlhon x3 but be limited to an am3+ cpu which atm are performing sub par compared with the competition.

wish they'd just ditch the current strategy once they finish with the current FX course and just start from the ground up with a new cpu, chipset, and socket, and see how that goes rather than trying to make something that has to work with a given board and all.

Yeah thats fair enough but I don't know if they have the cash to risk on starting from the ground up again and not succeeding if they did they might not survive maybe their current strategy will allow them to come back stronger in the future.

or they will crash and burn...
 
Funds for the next major upgrade will determine what I go with. At the moment my Phenom II x4 is perfectly fine for me, and I can game on high without a problem for basically anything. Having realized the performance of Sandy Bridge over the last year or so, which is making me consider going with Intel if I can afford it.
 
Here are some examples of failing amd's in floating points maths, integer maths is most used though. It's always a combination of the 2.
Compared to some intels.

Even the 1st gen is better at floating point

And the core2quad:

But they did make improvement in comparison to the athlon 64. But still not enough...

If AMD worked on the floating point, they'd be a way faster. That's what intel did too, the i7 920 had also bad timings in floating point. But they solved that with the sandy bridge, where amd was stuck, only the increase of speed made it maybe 10% better. Not enough to compete.

AMD will have to fix that before going further, it's not only power you need.
Every single part of a total process is important.
Everything is a combination of many things working together, amd has to look at every part separately before they combine it.

Just my own explanation, I can be wrong. But there is seriously something with their floating point maths, something that let them down.

Well my Phenom 1090T cpu cost £133 about a year ago which according to google is about $199, the Bulldozer is apparently a massive disappointment, and I don't see a lot else, although I have been wondering about the AMD Trinity, I don't know if it's any good, I might have a look into it now
 
That was my choice for upgrading but from what i could tell it was not going to be worth it for me to go from a 955 to a 1090T in terms of money, so i just saved money and went with a intel platform. Still have to figure out what to do with the old motherboard and CPU.

What about my improved scores from V3.2?
