	Scalefour Digest 1.2 'P4 Track and Wheel Standards' (Site not responding. Last check: 2007-11-01)
		The P4 recommended track and wheel standards are given in table 1, and are conditional on the use of the railhead contour(s) and tyre profile shown in figure 1.
		The most important single factor in ensuring reliable P4 operation is the maintenance of the correct tyre and railhead contours, and the successful use of the P4 track and wheel standards is conditional on the use of the scaled-down equivalents of these contours, as given in figure 1.
		In the formulation of P4 standards, a nominal clearance value of 0.25mm was adopted, in order to take account of the less than prototype equivalent track radii used in models, and the accuracy to which the wheelset BB could reasonably be expected to be maintained within the specified maximum.

		Scale is the model's measurement as a proportion to the original, while gauge is the measurement between the two running rails of the track.
		Official scales for the various gauges were soon drawn up, but the scales were not at first at all rigidly followed, and were not necessarily correctly proportioned for the rail gauge chosen.
		This, EM gauge and P4 scale are all 4mm scale standards; the scale is the same, but the track standards are incompatible.

	Scale size - Scale Models
		This scale was the first recognised scale in the real miniature sizes and was developed as long ago as the mid to late 1930s.
		This is the true gauge for the scale of 4mm to 1ft.
		The old Gauge 0 models are now referred to as coarse scale and the newer ones are generally built to finer scale standards with nearer to scale wheel profiles.

		The chromatic scale consists of all the 12 notes, 7 from the diatonic and 5 flatted or sharped.
		These are noted as u, o, p4 and p5 respectively.
		The first thing you should notice are the intervals between succeeding open strings: e-a : p4, a-d : p4, d-g : p4, g-b : M3, b-e : p4 So all the intervals are perfect fourths except the one between g and b which is a major third.

	The Ferrari P4 in Miniature
		The Ferrari P4 story is actually the story of the P2 and P3 models as well.
		For 1967, Ferrari introduced the P4 and while they had to settle for second at Le Mans to the Fords, a 1-2-3 finish at the 24 Hours of Daytona helped to make up for Ford's 1-2-3 finish at Le Mans in 1966.
		This model was the only P4 I had for many years and even if it was holding a place for these better models, it still deserves respect.

	Sharky Extreme - '+$ArtG+' - '+$ArtC+' - '+$ArtN+'
		As far as mucho better scaling, I have to agree, although seeing as how their 2Ghz had the 133fsb, it's not a fair and direct scaling, so unless Intel does move to a 133fsb, I wouldn't expect their 2Ghz to perform quite as well.
		Current benchmarks show the P4 with a slight edge in overall performance, but I don't think there is any doubt that the.18 Cu process AMD is using for TBirds is better then the.18 Al process Intel is using to produce the P4.

	HardwareCentral Forums - Seems we were wrong about the pipeline depth in the K8?
		It isn't so much that P4 has tons more stages than K7 or K8, it is more that P4 is designed to scale higher, not do more.
		If you are an engineer and you are told to design a processor with the number one criteria being high clock speed, you will do things a little different than if you are simply trying to get the highest performance out of the chip.
		Another slight misguidance here is that while K7/K8 have 3 x86 decoders to P4's one, P4 has an op code level trace cache with pre-decoded ops while K7/K8 must decode on the fly the instructions they receive from both memory and cache.

	Cell, 4,3Ghz with 1,3 vcore
		Think how the P4 can scale further due to it's low IPC and longer pipeline, now imagine a cluster of them with probably a lower IPC and yet longer pipelines each with more registers and also working as a single CPU...
		For example, four or eight P4 3.06 CPUs on a single core would, all else being equal, yield four to eight times the heat genereated by one core.
		You could reduce the IPC of the P4 cores and reduce the amount of heat generated by the group, but the overall effectiveness would also be diminished.

	GameSpy.com - Article: Pentium4 First Look
		The key idea to understand the reasoning behind all the new technology is that Intel is planning to keep the P4 around for quite some time, with large jumps in speed grades coming every few months.
		The core is designed to scale extremely well with increased clock frequencies, as well as die shrinks - which is a different approach than Intel had with the Pentium3.
		Needless to say, this new approach is something new in processor design - and should help the P4 to scale easier with clock frequency increases.

		The odd thing is that the SiS 648FX chipset the New Area-51m uses and the P4 800 FSB proc it uses both support HT, so hardware-wise it should be there.
		But there were stories that the old AW Area-51m with the 3.06 HT proc came with HT disabled, so maybe AW has difficulties with HT.
		Of course, the 8890 has a 3.2 P4 In the large majority of processor-intensive cases, HT should give you somewhere in the 40-80% range of improvement over non-HT.

	DriverHeaven.net - AMD's Athlon FX beats Intel's Pentium 4 3.2 GHz in almost every way
		The XP was (is) a really good processor however i always felt AMD couldnt scale it as fast as they needed where as Intel gave me a feeling that they can scale the p4 as fast as they want.
		I wouldnt be surprised if the FX comes out and leaves a p4 3.2 lagging behind and a very short while later Intel are anouncing and shipping processors in excess of 3.6ghz that take back the benchmark crown.
		It should scale well (being at the beginning of it's life) but how quick and in which direction is to be seen.

		However, the delta that exists between the Athlon 64 and P4 scores, is indicative of this test's emphasis on compression and decompression functions, like those found in video conversion, which is the P4's strong suit.
		We could point to the developers at Egosoft for this variance, since perhaps their main development vehicle may have been the P4 and as a result, X2's engine code is better optimized for it.
		We've shown you today that Prescott seems to be faster in certain situations than a Northwood P4 based processor and slower in cases where cache sizes aren't taken advantage of and where legacy code is less efficient on the new deeper pipelined architecture.

		All scaled the amount of transistors, clock speed and cache included on the chip, theoretically scaling the power and speed at the same time.

		Intel was betting that media and online programmes would make great use of the long pipeline in the architecture, but that turned out not to be the case, as performance suffered from repeated pipeline stalls.

		Like when the original P4 first came out, people liked to indicate that it didn't significantly outperform the P3 (and assumed that the P4 would NEVER be a good CPU based on that single occurance).
		Given that a 2.25GHz AXP can match the performance of a 3.06GHz P4 under certain applications, it is reasonable to assume that a 2.25GHz P3 (if it could scale as well) would do the same.
		My original point is that the P4 didn't perform well at lower (1.4/1.5GHz) clock speeds and it doesn't seem to scale well at higher clock speeds.

	Chipset Strategy Key to P4 Ramp - 12/11/2000 - Electronic News (Site not responding. Last check: 2007-11-01)
		Right now it seems the segments will be P4 and Rambus for high-end computing, DDR for the mainstream and PC-133 SDRAM for the lowest price-points.
		Since Intel continues to reiterate that the P4 was designed for performance-intensive applications and not the mundane MS Office, Rambus continues to be the memory of choice.
		The latency problem is tied to the design of the internal core architecture of P4, which contains a longer pipeline compared to the Pentium III and Advanced Micro Devices Inc.'s Athlon.

		Comparing to another post here with a P4 1.6@2324 with 4324/1214 (2845 SSE2), I'm thinking I'll get about the same performance for a given task.
		In your case, it seems that you'd have to spend hundreds and hundreds of dollars on a P4 system to get a noticeable increase in performance in much of anything to beat a 1333 Athlon at stuff.
		Sure, it may make bigger numbers on benchmarks and 3DMark scores and whatnot, but you'd have to go pretty far up the scale on P4 systems to get better real-world performance.
