[AMD] Exposing the Phantom x86 Bottleneck

post #1 of 42
Thread Starter 
This article is a blog post of AMD's Godfrey Cheng, his take on the state of affairs in the x86 world. I agree more with some things, less with others... reading it would make AMD's 2011 strategy clearer.

sneak peek:

[...]
The first 25 years of personal computing revolved around x86 performance. If you had a fast x86 CPU, you generally had the best experience. It wasn’t until the invention of the modern GPU in the mid-2000’s that another piece of silicon could effectively offload tasks from the x86 CPU.
[...]
I would classify these classic x86 workloads as short and “bursty†in nature. The CPU sits and waits until you hit that “Enter†key and then it scrambles to execute your commands. Does it surprise you that the vast majority of time a modern computer sits around and idles while awaiting your command? Even after you hit “Enter†or click the mouse to start an action, the work is done basically before you can blink. Since this is how quick most modern x86 based CPUs workloads are executed, the difference in performance for different brands of x86 processors is virtually indistinguishable for an average user.
[...]
AMD’s “Llano†and Intel’s “Sandy Bridge†are roughly equal in size and transistor count. But that’s where the similarities end. An analysis of the two components’ die area shows that AMD has invested much more heavily in graphics, parallel compute and video whereas Intel has invested much more of its silicon area in improving classic x86 performance.

Nice, so what they're saying is that an equivalent Intel chip will stomp on them with straight X86 benchmarks, but the Llano and Bulldozer will beat the Intel hands down for multi-tasking. Add in the fact that Intel's onboard graphics give my vacuum cleaner fits of envy at their sucking power, and this is a winner.

It will cost more money, power, and complexity. Besides, AMD is one two primary members of the discrete GPU oligolpoly.



What AMD is really saying is.... they are giving up on the server and HPC market then. x86 performance is a bottleneck there.

I don't think this statement has anything to do with server or enthusiast chips,so why would this mean they don't care about the server market?That is what Bulldozer,not Llano are for.

^This.

The article is about the x86 bottleneck for the average customer. AMD is saying this bottleneck is a myth and doesn't exist for modern workloads. TRUE.

For enthusiasts or the server market (where it does exist) they are releasing bulldozer. Read the article closely. They clearly state Bulldozer is aimed at better x86 performance.

I can agree with this fully, Really for an average consumer perspective 90% probably don't need more than a Core 2 Duo or an Athlon Dual core at most.

I totally agree with this. I have my sig rig at home and play games and everything on it, and at work I built a 2GB Sempron 145 system and unlocked it to an Athlon II x2 (2.8GHz). I can tell you from normal tasks (web browsing, office, flash videos, etc.) I do not notice any difference aside from load times in which case my sig has an SSD that destorys. Most people do not need the horsepower we on OCN have.

Do people who use their computers for gaming and other graphic intensive things REALLY use integrated graphics? And haven't they been putting dedicated graphics in laptops for a while anyway? For example, Apple uses Intel core series processors with discrete AMD graphics, 6490M and 6750M, in their macbook pros. Apple actually uses the integrated graphics for normal tasks, but when it becomes graphic intensive it starts utilizing the discrete GPU.

Edit: I understand this article is about the average consumer and agree most people don't need a powerhouse, so I can see how it would be an advantage to AMD to make better integrated graphics to further reduce costs to your average consumer while more than meeting their needs... Sadly I'm sure many big manufacturers will still charge the same price as if they had a decent dedicated GPU in the system.

Not necessarily. Given CPUs like Magny Cours. The idea there is massive x86 performance using more cores. Since each core provides more performance/watt than Intel cores and there are more of them, it's still a winner. In server workloads multi-core is more valuable too. With Bulldozer's architecture wielding more integral processors, it should scale very well.
