[Computerbase] AMD's outlook for faster "Bulldozer" successor - Page 12

post #111 of 125
AMD might not be so good for performance. Their ATI division is doing great.

Maybe they need to focus on performance/watt ratio rather than more CPUs.

This reminds me a lot of Pentium4 VS Athlon. Its sad that its the other way around.

I've always had Intel. I don't hate AMD, but I don't know why anyone would get a bulldozer (I started building after C2D, if it was a little before I would have gotten the Athlon).

It was the six core 1366 chips (i.e the 980x). In terms of total output, they're much faster than Sandybridge currently. IPC is still identical to Nehalem, though, so you'll see a 2600k or 2500k pull slightly ahead in applications that don't use many threads.
SNB's IPC is ~20% faster than Nehalem's. We were able to surmise this back in 2010 before SNB launched.

When you consider all other interconnects and buses across the entire chip like the cache, memory controller, and SMT, the entire chip is probably slighter more than 20% faster.

It's a 100% increase over the A4 at the same clock speeds, at the lowest point.

They may not care about single threaded increases much, but it still boils down to just that. If a CPU has lower single threaded speeds than it's previous generation, yet more cores, like with this launch, you see only a marginal increase. Whereas, Intel has been all about increasing single threaded power, therefor when it comes time for all four cores to be used, they gain performance even further. I just don't understand how the engineers thought this was going to pull off.

Seriously, The hell AMD?
A5 is a dual core A4 is single, enough said....

4) They should have released a matured architecture in 2012 with Piledriver

What do you guys think?
Pretty much right on the mark, I think. AMD rushed this out the door, like Intel did with the original Pentium 4, and BD has the same kinds of problems. Nothing is optimized for it, and they clearly haven't had time to address the issues.

i agrree except ur underselleing AMD just a bit -.-, they are a decent alternative

I am still on AMD because the integrated GPU in llano offers triple monitor support and a lot more performance and features then intel. I am a niche user though, an enthusiast who will likely never get another discrete graphics card again (if I can avoid it). I can't see a reason to recommend AMD CPU anymore. Intel is just way better and they are only going to get further and further ahead.
post #117 of 125
man, I was pretty sure AMD can pull something a little better than semi-flop with Bulldozer.

perhaps it is time to finish my intel build.

I hope Piledriver sticks to AM3+, I'm sure as hell not going to buy another Motherboard

People always seem to forget that AMD is just as shady as Intel. They've gotten caught in the price fixing game multiple times now.

I wouldn't hold my breath on 10-15% boost with Piledriver either.

But can you actually call it an 8 core CPU?
We seem to be expecting it to perform as though it has 8 cores all with ALU/FPU, and it's not.

The third is that the CPU (apparently) can't effectively use all the available integer cores due to poor scheduling by the OS, large cache latencies, not enough decoders, and poor branch prediction. That is to say that the integer units are being bottlenecked.
I remember when we put a 68882 (FPU card) in our 16MHz 68030 LCII. The difference in performance was absolutely staggering. Maelstrom was nearly fluid on level 40 and spreadsheets that took 3 or more minutes to run took only 1 to 1.5 minutes to run.
