The Chip That Changed the World: AMD's 64-bit FX-51, Ten Years Later
Dputiger writes "It's been a decade since AMD's Athlon 64 FX-51 debuted — and launched the 64-bit x86 extensions that power the desktop and laptop world today. After a year of being bludgeoned by the P4, AMD roared back with a vengeance, kicking off a brief golden age for its own products, and seizing significant market share in desktops and servers."
Although the Opteron was around before, it cost a pretty penny. I'm not sure it's fair to say that the P4 was really bludgeoning the Athlon XP though (higher clock speeds, but NetBurst is everyone's favorite Intel microarchitecture to hate). Check out the Athlon 64 FX review roundup from 2003.
Those were the good old days. How I miss when it took me one day at most to learn about all options I had to build a gaming computer, with enough detail to make an informed decision about what bits and pieces to built it with.
Nowadays just piercing the veil of lies, half truths, false reports and bought reviews, makes the entire process incredibly boring and frustrating.
It seems we've lost a lot of quality in the comment fields in the last 10 years. Lots of expertise modded up carefully; now we seemingly have opinion-pieces moderated up by whichever group happens to be awake at the time, and the real expertise is hidden in the +2 or below.
AMD is very competitive for many-cores workloads. To get an equivalent core count on Intel can be as much as a second AMD system. AMD has gone more wide, Intel has gone more deep. Both have their applications.
My God, it's Full of Source!

10 years later and we're still running games and applications that are 32bit that only use a single core.
For games sure, but there are lots of workloads that are not games.
As the author of the article:
In 2000 - 2001, the Athlon / Athlon XP were far ahead of the P4. But from Jan 2002 to March 2003, Intel increased the P4's clock speed by 60% and introduced Hyper-Threading. SSE2 became more popular during the same time. As a result, the P4 was far ahead of Athlon XP by the spring of the year in most content creation, business, and definitely 3D rendering workloads. Now it's true that an awful lot of benchmark shenanigans were going on at the same time, and the difference between the two cores was much smaller in high-end gaming. But if you wanted the best 'all around' CPU, the P4 Northwood + HT at 2.8 - 3.2GHz was the way to go. Northwoods were also good overclockers -- it was common to pick up a 2.4GHz P4 and clock it to 3 - 3.2GHz with HT.
Athlon 64 kicked off the process of changing that, but what really did the trick was 1). Prescott's slide backwards as far as IPC and thermals and 2) The introduction of dual-core. It really was a one-two punch -- Intel couldn't put two Pentium 4 3.8GHz chips on a die together, so the 820 Prescott was just 3.2GHz. AMD, meanwhile, *could* put a pair of 2.4GHz Athlon 64's on a single chip. Combine that with Prescott's terrible efficiency, and suddenly the Athlon 64 was hammering into the P4 in every workload.
AMD, forgotten by most of you, purchased a CPU design company not long after it lost the right to clone Intel CPU designs. The people from this company gave AMD a world beating x86 architecture that became the Athlon XP and then Athlon 64 (and true first x86 dual core), thrashing Intel even though AMD was spending less than ONE-HUNDREDTH of Intel's R&D spend.
What happened? AMD top management sabotaged ALL future progress on new AMD CPUs, in order to maximise salaries, bonuses and pensions. A tiny clique of cynical self-serving scumbags ruined every advantage AMD had gained over Intel for more than 5 years afterwards. Eventually AMD replaced its top management, but by that time it was too late for the CPU. Obviously, AMD had far more success on the GPU side after buying ATI. (PS note that ATI had an identical rise to success, when that company also bought a GPU design team that became responsible for ALL of ATI's world-beating GPU designs. Neither AMD nor ATI initially had in-house talent good enough to produce first rate designs.)
Today, AMD is ALMOST back on track. It's Kaveri chip (2014) will be the most compelling part for all mains powered PCs below high-end/serious gaming. In the mobile space, Intel seems likely to have the power-consumption advantage (for x86) across the next 1.5 years at least. However, even this is complicated by the fact that Nvidia is ARM, and AMD is following Nvidia, and is soon to combine its world beating GPU with ARM CPU cores.
At this exact moment, AMD can only compete on price in the CPU market. Loaded, its chips use TWICE the power of Intel parts. In heavy gaming, average Intel i5 chips (4-core) usually wallop AMD's best 8-cores. In other heavy apps, AMD at best draws equal, but just as commonly lags Intel.
Where AMD currently exterminates Intel is with SoC designs. AMD won total control of the console market, providing the chips for Nintendo, Sony and Microsoft. Intel (and Nvidia) were literally NOT in the running for these contracts, having nothing usable to offer, even at higher prices or lower performance.
AMD is currently improving the 'bulldozer' CPU architecture once again for the Kaveri 4-core (+ massive integrated GPU and 256-bit bus) parts of 2014. There is every reason to think this new CPU design will be at rough parity with Intel's Sandybridge, in which case Intel will be in serious trouble in the mains-powered desktop market.
Intel is in a slow but fatal decline. Intel is currently selling its new 'atom' chips below cost (illegal, but Intel just swallows the court fines) in an attempt to take on ARM, but even though Intel's 'atom' chips are actually Sandybridge class, and have a process advantage, they are slaughtered by Apple's new A7 ARM chip found in the latest iPhones. A7 uses the latest ARM-64 bit design known as ARMv8, making the A7 and excellent point of comparison with the original Athlon 64 from years back.
Again, AMD is now x86 *and* ARM. AMD has two completely distinct and good x86 architectures ('stars-class' and 'bulldozer-class'. Intel is only x86, and now with the latest 'Atom' has only ONE x86 architecture in its worthwhile future lineup. Intel has other x86 architectures, but they are complete no-hopers like the original Atom family, the hilariously awful Larabee family, and the putrid new micro-controller family. Only Intel's current sandybridge/ivybridge/haswell/new-atom architecture has any value.
Apple just released a 64bit processor, and now AMD is copying it TEN YEARS ago?!?
Can the industry please do something original and quit just following wherever Apple leads it?

The spec benchmarks tell a different story, and tend to be more representative because each vendor does their best rather than intel/nvidia providing "free" performance enhancement advice for game companies.
So, from my own experience the Amd/Intel story is a lot closer than some of these benchmarks might lead you to believe. Especially for server applications.
Its pretty easy with modern CPU's to make fairly small tweaks that give advantage to one CPU or another. We have a bunch of microbenchmarks for our application, and things like memcpy performance can be swung 2x-4x. Or even the depth of loop unrolling for some things. In one loop the intel it may like 2x and the AMD like 4x unroll. With each one tuned to run best on the platform the bottom line performance is often quite similar, but run the AMD optimized one on the intel, or the reverse and suddenly one or the other CPU appears to be trouncing the other.
Ok, I'm a Java developer, working on Linux. 99% of benchmarks you see on-line are benchmarks of some stuff on Windows, which is immediately skewed towards intel because lots of Windows DLLs are built with Intel compiler which disables optimizations and advanced features on non-intel CPUs, even if those features are supported.
Also, most benchmarks are some synthetic benchmarks (compiled with Intel compiler), or some 3D games, or some video transcoding. I do none of that, and what I do I do not do it on Windows. I am yet to see a site that benchmarks Java compilers, Java IDEs, databases, application or Java web servers, etc. on Intel vs AMD vs ARM platforms on Linux. The only site that comes close is Phoronix. And if you look at their Linux benchmarks, difference between AMD and Intel CPUs is much less than on Anandtech or Toms Hardware. Intel is still making faster CPUs, but not that much faster.

Unfortunately, not everyone has the ready cash available to buy every CPU, set up a complete system for each, and benchmark them. We plebians have to rely on other people to do that kind of testing for us. And when a great deal of websites, all doing independent benchmarks and reviews, all show AMD getting their collective asses handed to them on a regular basis at the moment, I tend to lend those reviews some weight.
They swooped in when Intel was being stupid, made the best chips in the world... then committed suicide and
If, by committed suicide, you mean that suffered when intel bribed people like Dell not to use the clearly superior products and so lots out on many billions of sales and hence the crucial R&D advantage, then yeah sure suicide.
Assisted suicide.
Like assisted like throwing a healthy happy person off a clifff.
haven't built a competitive chip in 3 years. Sad times...
Depends what for. For games, intel seem to be better IF you're prepared to buy a separate GPU. If you look on the Linux, not Window centric benchmarks, the top end AMD ones often lie somewhere between the top end i5 and the top end i7.
Sometimes they lose out sometimes thy beat the i7s.
For the kind of stuff I do, they're very competitive.
But if you play skyrim, then no. But an i5 and an external graphics card.
