To readers well-known, that in the end of January the Canadian company ATI has presented new family of accelerators for desktop systems - RADEON X1900. The structure of a ruler included at once three cards: RADEON X19 XTX (the most powerful accelerator), RADEON X19 XT (little bit more poorly) and RADEON X19 XT CrossFire Edition. First two products we is already detailed Have studied, and here technologies CrossFire, but already in ispolneni We already earlier considered technology, therefore we shall not stop on it. Briefly only I shall tell, that it is a certain analogue of technology NVIDIA SLI when two accelerators unite the efforts on processing motion notebook picture three-dimensional schedules, and the final result turns out in an ideal above in times (really, certainly, prirosty' less for to that there is a number of the reasons: and feature of this or that game, and an emphasis of productivity in CPU (system resources), etc.). At processing a stage work between cards shares different ways, and all it the driver manages. SLI from NVIDIA enables or to divide Horizontally stage on two pieces, which sizes can flexibly vary depending on current requirements of game to the accelerator; or rendering It is carried out by each accelerator in full (a stage entirely), but alternately (the even staff - one, odd - the second). At CrossFire To these two modes the third is still added - division of a stage into squares in chessboard order, and thus division of motion notebook picture work between videocards. This all - is brief, for simplification, details - read in a base material on CrossFire. It is known, that technology SLI has a number of advantages: first, it has really appeared earlier, and already has had time to grow roots, and drivers were essentially updated, and support SLI has strongly got stronger. Secondly, for SLI the special card, there enough any two videocards on identical GPU (from GeForce 6600LE and above) is not required. All these pluss at SLI automatically become minuses for CrossFire (CF). Also there was a technology very much late, and support unimportant, and is presented Was on become outdated already X850-kartah. Plus obligatory presence special master-karty' - CF Edition. But it was even motion notebook picture in the summer and in the beginning of autumn of 2005. Now the situation has exchanged. First of all, it is necessary to tell, that new ruler X19 at once in itself includes CF Edition the decision, and really such cards already are, and have gone on sale simultaneously with usual X19 XT/XTX. Therefore interested persons in the future (or already now) create such tandem from two cards can to buy at once and CF Edition and usual X1900. To get XTX it is useless, as all the same all sparka will work on frequencies XT (in fact CF Edition it is those). By the way, already for this motion notebook picture reason it is possible to tell, that X19 CF it turns out formally a duet not the strongest accelerators from ATI. But about it later. There is also other party of a question: a system payment. For today an obligatory condition for CF is presence materinki on the basis of ATI RD4 or i975. Besides, the late output and not strongly active distribution of such payments is the certain obstacle. Someone is already obvious, that hardly, already having system, we shall admit, on NForce or i955, begins to pass to another materinku for the sake of CF. That who now plans to replace old AGP-platformu with something new with the purpose to receive the motion notebook picture most powerful game system, I advise already to think, on what to pass. CF it can appear not the worst variant. However, here to solve to users for the price and availability of this or that component has huge value. Neither SLI, nor CF, do not possess so bright outstanding features for the sake of which it is possible to go and on decent expenses even if it will appear more expensively. So, CF is a complete set: the system payment, two videocards and ON. The last - usual the driver, therefore anything especial in them is not present, videocards: One of them CF Edition, we such just also shall study. The system payment - will be also briefly considered below Frequencies (chip/fizicheskaya on memory (effective on memory): 625/7 (1450) MHz (face value of 625/7 (1450) MHz So, we see, that X19 XT CFE - as a matter of motion notebook picture fact, same private soldier X19 XT, but for the sake of technology CF deprived VIVO and even TV-out. Such technical videocard, without habitual additions. Whether a minus it? I think, that was not present. If someone plans to establish CF later, that is to buy cards by turns in the beginning it is necessary to get usual X19 XT, possessing VIVO, and then CF Edition a product. The card is equipped by two jacks DVI (certainly, Dual-Link). And, one of jacks - special: Into it it is inserted special adapter-kompozer, Which one tail goes on the second videocard (DVI), and other tail serves for connection of the monitor. So this all looks in gathering (while outside of the system block). CF Edition motion notebook picture it is necessary to put in distant from the processor slot. By the way, already second time I notice, that at ATI in this plan all is turned: sloty' begin not from CPU, and on the contrary, all GPU cost head over heels on videocards. That this all meant?: I think what to study system of cooling it be no point, all is standard, I already earlier told about tako Before us engineering still sample R580, precisely same, that is established on all X19 XT/XTX. In fact all distinction between CFE and usual cards Consists in PCB and it obvyazke the additional elements which are carrying out assembly of slices in a uniform three-dimensional stage Computer on the basis of Athlon (939Socket) processor AMD Athlon 40 + (2400MHz) (L2=1024K) Operative motion notebook picture memory GB DDR SDRAM 400MHz (CAS (tCL) =2.5; RAS to CAS delay (tRCD) =3; Row Precharge (tRP) =3; tRAS=6) Monitors ViewSonic P8 (21) and Mitsubishi Diamond Pro 2070sb (21) Monitoring shows us, certainly, that heating of a card is very great. Over degrees under loading! But once again I shall note, that main positive Feature of system of cooling - emission of hot air outside, therefore especially to worry there is no reason. Besides, turns of a cooler rise daj Results of tests: comparison of productivity Not a secret, that many games have already rested against opportunities CPU and systems as a whole, and consequently on The most powerful accelerators even in modes with AA 4h and AF 16h we do not see potential of these accelerators. Therefore we have entered new mode HQ (Hig ATI RADEON X1xxx: AA 6x, plus Adaptive AA, plus AF 16x High Quality It, as a matter motion notebook picture of fact, as much as possible, that accelerators from ATI last generation can show all NVIDIA GeForce 78 GTX 5 SLI it is presented on the basis of cards from Gainward to series Golden Sample, the poet 03, testing was spent at the maximal quality, an option-dxlevel 90, in a file dxsupport.cfg presets for kinds of cards) are cleaned demo from levels Research, Pier, Regulator (start of game with an option-DEVMODE), adjustments of testing all Very High. There is an example of automation of start with increase in speed and reduction of number ry'vko (TO NOT be frightened the black screen after the first menu, and should be!

F.E.A.R. Results of tests: F.E.A.R. Feedback from CF is rather quite good, though nevertheless at a level no more than %. As to battle with 7800GTX 5 SLI, a situation raznorechivaya, however Nevertheless a victory for CF as such SLI it will be obvious more dearly Splinter Cell Chaos Theory Results of tests: SCCT very quite good prirosty' on speed has given CF, however SLI nevertheless has not given a pure victory, the parity has turned out. Though it is necessary to remember, that is veroyatnost Call Of Duty DEMO Results of tests: COD the Picture similar, and even it is possible to ascertain victory SLI over a motion notebook picture duel Half-Life2: demo Results of tests: Half-Life2, Game very much processorozavisimaya, therefore only mode HQ has enabled a tandem of accelerators not bad to show the potential The game tests strongly loading piksel'ny'y the conveyor teksturirovaniem, active work stensil'-bufera, blocks sheyderov Chronicles of Riddick, demo Results of tests: Chronicles of Riddick, demo Feedback from CF is very great, but nevertheless koronny'y API NVIDIA - OpenGL has an effect, and if in DOOM III the provisional parity between SLI and CF, in CR already overweight on the party of the decision from NVIDIA is still observed. Alas, but OGL-igry' probably, up to the end will be a headache for the Canadian company. 3DMark05: MARKS Results of tests: 3DMark MARKS it is surprising, but feedback from CF is not so great, as it motion notebook picture was possible to expect, from SLI it above, therefore besides, that otdel'n X19 XT is stronger, che 3DMark06: MARKS Results of tests: 3DMark MARKS Snader Model 2. Snader Model 3. In the block of tests SM2. CF has brought osch'utimy'e dividends, but nevertheless SLI was again more effective, and consequently equality of forces, eventually, has turned out. SM3. Has brought success already CF as in this case and separate X19 XT is stronger, than the contender from stana NVIDIA, and does not work HDR Conclusions So: ATI CrossFire on the basis of RADEON X19 XT, 2x512MB - the fastest for today a tandem of graphic accelerators three-dimensional the schedule Yes, somewhere it concedes to similar duet GeForce 78 GTX 512MB, but as a whole nevertheless is little bit more powerful, besides SLI works on the raised frequencies. Against usual 78 GTX 512MB motion notebook picture SLI certainly, CF will look the obvious winner. But whether such expenses for purchase of two accelerators are justified to receive feedback on the average in 65- % of a gain of productivity? I believe what to answer this question there is no sense as all the same to pay almost 15 dollars for such video subsystem of a computer of very few people can, and if someone and will want, it is the enthusiast or the fan of games and consequently its any percent do not stop. We already spoke about pluss and minuses above, they are clear and transparent. For example, put me before a problem of a choice if to change all platform entirely, could not solve easily such question even if two cards equally (and now would cost while there is all chances to consider, what motion notebook picture even in the beginning of sales the price on X19 XT can be below, than on 7800GTX 512MB because of deficiency of the last). Therefore a choice for readers. We have told everything, that could about new technology and its embodiment. And certainly, do not forget about gluttony of such cards! One X19 XT consumes above 120Vt, therefore for CF very solid power units (precisely above 500-600Vt) be required. And when already work above a material came to an end, one idea has come: unless so it was difficult to make, we shall admit, all X1900-karty' CrossFire Edition? To place VIVO and kompozing on one PCB - a problem quite possible, top jack Dual-DVI can be used also and without installation CF - the monitor To connect through an adapter. Will increase this all the cost price no motion notebook picture more than by dollars, at the prices in 6 dollars is mizer. But there are no problems with search so-called master-kart, any two X19 can be put in CF. And in general this price on X19 XT CFE which above, than at X19 XT for dollars, seems to me is great. Anything superdear on a card is not present! Besides, it is necessary to subtract cost Rage Theater which is not used at CFE. And consequently overestimate of the price looks only a certain marketing course. The variant is possible, that CFE cards will be compelled to sell even more cheaply usual X19 XT in view of absence of demand, for now very much many lyud And other classes you can see fuller comparative characteristics motion notebook picture of videocards of it also Functional features GPU ATI RADEON X18 (R520) / RADEON X19 (R580) / X16 (RV530) / X13 (RV515) and NVIDIA GeForce 68 (NV40/45) / 78 (G70) / 66 (NV43) Memory dl Andrey Vorobev (anvakams@ .com) It is published on February, 2nd, 20 Other discussions in conference:
