Intel's Conroe Previewed and Benchmarked
DrFishstik writes "Anandtech has a few preliminary benchmarks on Intel's new Conroe architecture. From the article: 'As far as we could tell, there was nothing fishy going on with the benchmarks or the install. Both systems [AMD 2.8Ghz OC and Conroe] were clean and used the latest versions of all of the drivers.'"
As pointed out by Ars http://arstechnica.com/news.ars/post/20060307-6334 .html I think we should wait and see for the more objective benchmarks. Anyway 2006 will be a good year for CPUs
by the time this new intel is out, AMD should already be well and truly released. probably also embedding themselves more in Dell's good books and taking more than 80% of the market. Intel are fighting the loosing battle.
1) AMD has something like 20% of the processor market, including OEMs. They couldn't deliver 80% of the market in many years even if the market wanted it.
2) AMD has no major process/architecture shifts between now and Conroe's release.
3) The AMD chip was already overclocked (but then again, they may have gotten a golden sample from Intel).
4) It's losing, not loosing.
Live today, because you never know what tomorrow brings
Did they really expect around 20% better performance, while using 66% faster RAM? That seems at least unfair to me... Especially the encoding tests, whose results depend heavily on RAM access.
If you read the various benchmarks over the years, changing memory architecture or increasing it's speed directly does very little to increase most benchmarks more than a percentage point or two. Inceasing FSB also hasn't done much. Rather increases in processor performance are directly responsible for the disparity between the new Intel cpus coming.
The AMD was overclocked to the timings of the one that won't officially be released until June - unsurprisingly, AMD won't let them have a pre-production chip to demonstrate how their one is even faster.
"I Know You Are But What Am I?"
I got a cheapy 64 bit sempron system with crappy onboard 6100 nVidia graphics card (theres an empty pci-e slot available for the summer)
:)
I held off playing half life 2 because I didn't think it would run (I had a 5900 agp previously than ran it really well)
I am running now at 800*600 with full details enabled and 2x AA and I've only noticed one point where it even shudders (the chimney blowing up and falling whilst in the airboat), if anything its smoother on this card than before, and the shaders are tonnes better (water, and nobbly glass doorways especially).
The only thing I'm missing is the ability to go to super resolution, but considering what I have gained I'm willing to wait.
I was very pleasantly surprised

old article indicated that it's actually x86 extension on 64bit processor, Conroe.
"Don't let fools fool you. They are the clever ones."
According to this, the 2.66 GHz Conroe will be released in Q3'06 at a price of US$530, in 1000-unit quantities.
With these prices, combined with the apparent performance and power differences (Conroe has a predicted TDP of 65W, compared to the FX60 at 110W), it looks to me like we'll finally see some heavy competition from Intel. Of course, a lot can happen between now and then - Intel have had manufacturing issues in the past, AMD have a new memory controller on the way and a 65nm die shrink due early next year, and can probably squeeze out two or even three speed bumps before Conroe really hits. Who knows, they might even drop their prices a bit.
Come Q3, I'll be sitting in the ringside seats with popcorn, ready to watch the fun :-)
Why would anyone engrave "Elbereth"?
The real hope for AMD here is that these results won't hold to other benchmarks in general. Apparently this set of benchmarks was handpicked by Intel, so that's almost certainly the case to some degree.
If you're referring to "Hyperthreading", Conroe has none that I'm aware of. One thread at a time, in hardware (whatever you like in software of course).
the power consumption and with that the heat output
Conroe is supposed to have a Thermal Design Power of only 65W. Compare this to the current 3.6GHz P4's TDP of 115W. AMD rate the Athlon FX60's TDP at 110W; however AMD quote the maximum possible thermal dissipation while Intel quotes "typical", usually 75% of maximum (which would make the FX60 about 82W by Intel's reckoning) .
of course the expense of both the processor and the ram it needs
The 2.4GHz and 2.6GHz Conroes are expected to sell for US$316 and US$530 respectively, in 1000-unit quantities (the FX60 was released at US$1031). RAM is harder; reportedly Conroe chipsets will use DDR2, but possibly packaged as new FB-DIMMs. I don't have pricing for those yet, but they'll probably cost more. Consumer motherboards may just use standard DDR2 DIMMs.
Why would anyone engrave "Elbereth"?
You should not forget that Intel supplied both the hardware and the benchmarks. Obviously, they will only supply benchmarks where they win, and not the ones where the Athlon is better (if there are any). The F.E.A.R. benchmark seems to confirm that Conroe is really faster, but that's just one benchmark, which is not enough to convince me of Conroe's superiority.
That being said, I think it is in everybody's best interest if the benchmark results actually represent a real advantage; 20% more speed is indeed a big step forward.
The article compared a AMD Athlon 64 X2 *NOT* a FX.
FX is known to be better in gaming than the X2.
The things that AMD has said that they have are F, G, and H revisions of the K8 core (the core that the Athlon64, Turion, Sempron64s, and Opterons are based on) which, other than DDR2 support, not much more information is available. There is another revision called the K8L which will supposedly have 2x the FPU units for about a 50% gain in FPU performance. These will most likely be HPC blade Opterons or some such.
DDR2-800 support, which is the known upgrade, basically adds bandwidth to a chip that isn't bandwidth starved as it is. Current speculation is that the new DDR2-800 Athlon64s will show up to a 10% performance increase on extreme bandwidth benchmarks (synthetics and HPC crunchers, for example).
THe simple fact remains that intel needed to do these tests at all, side by side. That's an admission on their part that AMD is beating them and beating them hard.
Intel has publicly stated (admitted) this already. This demo is to show that the chips they have planned for Q3'06 release (speculation is that they will be delivering machines based on it in July which is the very beginning of Q3, which is only 4 months away) perform well.
By the way, if speculation is that machines will be selling in July, this would imply that the chips are in manufacturing even as we speak. This means that Apple is most likely to announce availability of the new Intel based Power Macs around this time, as well and the various benchmark sites to have their hands on 'pre-production' machines in two to three months tops. We'll be able to see the real story then.
The only announced things from AMD even remotely in this time frame (specifically July and Q3'06) are the AM2 socket for DDR2-800 and a speed bump of the FX-62 to 2.8GHz (which is the equivalent of the overclocked part in the demo). Given that DDR2-800 is expected to be a 10% speed bump at most in most cases and that Conroe will be available at 3GHz (if not higher as rumored - 3.33GHz), I predict (a rather easy prediction to make) that AMD will be playing catch-up for once in the past few years.
Oh... another thing that I forgot was that somewhere in the F, G, and H revisions (and probably the L), HT was supposed to be bumped up to 333MHz (1.333GHz effective) from the current 200MHz (1GHz effective). Given that tests have already shown that 800MHz effective HT performance is statistically equal to 1000MHz effective HT performance, boosting HT speed will probably give a small (1% to 3%) performance increase at best. In actuality, the HT speed increase is required for DDR2-800 to run at its best so the performance gain for it is probably inclusive to any gains shown by DDR2-800 adoption.
As I explained yesterday, the TPM is not actually in the processor, but the processor has a few new features that allow it to cooperate with the TPM. If you buy a motherboard with a LaGrande-enabled processor but no TPM, LaGrande will not be able to work its evil magic on you.
You missed the part where the parent said "within a single architecture".
Intel's heat issues started when they introduced Prescott, which was effectively a new architecture that didn't really deserve the moniker "Pentium 4".
When you compare the current P4 to the original P4, they have very little in common. Intel just stuck the P4 name on all of them for marketing reasons. In fact, if I'm reading all the coverage of Conroe correctly, they are going to call it a P4 too even though it is a completely different architecture derived from the Pentium M (which is itself derived from the Pentium III).
So the parent's point remains valid. When you compare the various initial speeds of the Conroe, since they will all be based on the same core, comparing performance based on clockspeed (between Conroe chips) will be a valid comparison.
It was an FX-60 (overclocked to 2.8 GHz), which is pretty much identical to the Athlon64 X2 series with the sole exception of having unlocked multipliers to support overclocking. Hexus did a review of the same machines over at http://www.hexus.net/content/item.php?item=4843.
Intel has already stated that the Conroe will be dual-core only. The quad-core chip is called the Clovertown, and is due out next year (early 2007).
