DFI NT70-SA: perfecting to the maximum the Pentium 4

His publicity in CsH


Trying, trying

First of all, the forced list of used material:

  • Microprocessors: Pentium 4 to 1,4 GHz and 1,7 GHz (bus 400 MHz), Athlon to 1,2 GHz (bus 266 MHz)
  • Basic badges: DFI NT70-SA and DFI WT70-EC (chipset Intel 850), DFI AK76-SN (chipset AMD 760)
  • Memory: 256 MB RDRAM PC800 (Samsung), 256 MB DDR-SDRAM PC266 (Crucial)
  • Graphic card: GeForce2 MX400 (200/183 MHz)
  • Others: Windows 98, drivers NVIDIA Detonator

The Pentium 4 has now a good relation yield / price to 1,7 GHz... although we did not have many other options either, we were depending on what they wanted to give us (we have several proper mikes, but almost they all are AMD or Intel pre-Pentium 4). Of course, if he is going to buy a team Pentium 4 of the highest scale (if it can wear out SO MUCH), choose the model of 2 GHz "A" (with 0,13 microns nucleus).

Since we usually in the tests of basic badges, "what it counts is the stability of the badge and verify say that the yield is adapted to the secondhand chipset". In this respect, quite correct. Good yield and a PERFECT stability. Yes, without exaggerating: PERFECT stability, NO PROBLEM of no type (hangs, pantallazos blue...) in a pair of days of tests. One notices that we are before a motherboard destined for the demanding market OEM, in addition with one of the chipsets that better have gone out for Intel.

Of what it is not doubt someone is of the impressive band that it offers the Pentium 4. His theoretical 3,2 GB/s, although of course in practice we remain more or less in half of this value, gives for much in applications hard claimants in this aspect. More on this, next...


The market, the prices and the competition

With regard to other basic badges for Pentium 4 based on the chipset i850, we can say that the NT70-SA turns out to be very competitive. A really enviable set of characteristics, a phenomenal stability, certain details of quality and everything at a price relatively low, how does type OEM correspond to a good badge. He lacks possibilities of overclocking, but it does not play in this field and the Pentium 4 is not the best thing for it, at least in 0,18 microns.

On the other hand, now we have other chipsets available for Pentium 4, which innovation takes root in using other memoirs instead of the RDRAM (Rambus-DRAM). Of them, the worst it is i845 for SDRAM PC133, not advisable at all, since the minimal band of the above mentioned memory destroys the principal quality of the Pentium 4. Believe me, it would not be worth it nor given...: that is not the case, above is expensive!

The following one is the new one i845D for DDR-SDRAM, a good chipset but something expensive. We save ourselves some money for not using memory Rambus, but too much because it is a question of a chipset Intel, almost for definition slightly economic not also; and the band is good (2,1 GB/s), but not so good as 3,2 GB/s of i850.

The Intel competition has at present another two chipsets for DDR-SDRAM, SiS 645 and the "illegal one" (according to Intel) ROUTE P4X266A. Both are of very good yield and rather exact price, what it makes quite advisable to them... if and only if we are absolutely taken a fancy by the Pentium 4. Why do I say this? Very well, because it is a question of a mike much more expensive than the AMD Athlon XP, whom only it manages to overcome in applications that need the highest band... and as we were saying, that of the DDR-SDRAM is high, but not so much like that of the Rambus with double channel (i850).

And as for the mikes AMD, the question is clear: on the market of middle and low class, if it does not have special manias that prevent him from passing to this mark, there are the best in quality / price. If the money does not matter, the thing becomes slightly tougher; and if type treats video as applications, the Pentium 4 with chipset i850/RDRAM are unbeatable, thanks to (does it foresee it?) his 3,2 GB/s of band of memory and bus of mike to 400 MHz.

For that they wish the comparative one of the yield of the diverse chipsets for Pentium 4, we recommend this EXCELLENT article of Tom's Hardware; be fixed there how all the chipsets are more or less close, except the infamous one i845 with SDRAM... and how it separates i850 in the test of compression of video MPEG-4. It looks like little difference, but when it is a question of the HOURS that cost these works, ends up by being great.



Little stays for saying already; the NT70-SA is a very attractive, highly stable badge, with quality details, with all the characteristics that we might wish except the overclocking and with one of the least expensive prices between the badges with chipset i850.

... Because, undoubtedly, i850 + RDRAM will be an expensive solution, but it is still THE BEST for Pentium 4. After everything, if we do not make use of the band of the Pentium 4: why would we it buy demons, existing the Athlon XP? And fortunately, nowadays it is easy to find 256 MB 128 MB (2 modules) of memory RDRAM for approximately 115 euros (approximately 100 $) or less, which is not too much money. What was not a reasonable age to pay for it 10 times more, how year ago and a half happened...

Ah, since it is habitual in these times, DFI has developed the whole series of badges "to satisfy any user" from the same design, by means of the simple method of putting or not some chip and/or connector. If he does not need RAID and/or any more than 4 devices IDE, or if really it is not interesting to him to have network support, the series NT70 has 4 models, for all the tastes:

Anyway, a good offer to mount a stable and relatively accessible team destined for edition of video or simple ripeo of movies in DVD... only to do personal copies, of course;-p
