Dual X16 CrossFire - RD580DFI the Xpress 3,200 main engines boards are taken to the threshing ground the article: Thunder handsome @X16 Fever 2
The ATi official announcement promotes generation of newest AMD CrossFire platform Xpress 3,200, its cartography connection by the former generation double x8 promotion to double x16 PCI-E Lanes, the transmission frequency width enhancement reaches a time, actually are the Xpress 3,200 platforms whether the CrossFire technology bring in the potency the promotion! ? The editorial department looks for DFI LanParty the CFX3200 project sample to contrast the former generation RD480 platform.
The ATi plan vigorously develops the chip group enterprise, estimated the cartography chip income proportion will account for the overall income to drop to approximately 58% level.
ATi in 06 years on March 2 officially issued its new generation of AMD K8 CrossFire platform --- Xpress 3,200 (product code number is RD580), and held the Xpress 3,200 products release conferences to Taibei, at the meeting ATi chip group market department Manager William Tsao had disclosed ATi will put in more resources at the chip group enterprise, according to the material demonstrated ATi in the past 3 years gross income, mainly will be take draws a chart chip GPU as main, reached as high as above the overall income threes of four. But ATi will be able to push to multiplex in 06 years the product, chip group Chipset will be able by formerly only to occupy the whole 1,/10, expected the promotion to 5分之, the new product promoted the cycle also to be able the comparatively former frequency to be dense.
(There was some weird stuff in this paragraph that would not translate.)
According to William Tsao indicated that, the ATi chip group market share reached 3 times in the past 12 months growths, main growth lay in main OEM and the SI market, including HP, FSC and Acer was glad uses their product, lay in ATi according to William Tsao minute booklet its main superiority to have the integrity the product line, by Intel to AMD, Deesktop to extremely was all complete Notebook, Intergrated and Discrete, Vaule to Enthusiast, this was in the market other matches cannot compare. But ATi will be able to attack the AMD platform market with all one's strength, expected will strive for AMD the PCI-E platform approximately 50% market share.
ATi ︰ RD580 is only true double x16 the PCI-E platform! ?
ATi Xpress 3,200 will support double x16 the PCI-E cartography connection technology, will reduce because the frequency width drop to create the transmission the bottleneck
New generation of ATi CrossFire platform Xpress 3,200, its chip code number is RD580, contrasts former generation's main improvement to lie in on its cartography connection, former generation RD480 has used the X8 + x8 cartography connection design, when uses the sole indicator may group synthesize x8 + x8 PCI-E the Lanes PCI-E the x16 cartography connection, but under the CrossFire pattern, may establish two group of PCI-E the x8 cartography connection, but each group of connections frequency width is more normal than PCI-E x16 to reduce half to have 2GB/s.
But new generation of RD580 constructs 22 PCI-E by the former generation in the Lanes large promotion to the promotion to 40PCI-E, therefore it may promote the integrity x16 + the x16 cartography connection, under the CrossFire pattern, each group of connections frequency affable normal PCI-E cartography meets equally is 4GB/s, reduces creates the material transmission because of the frequency width drop the bottleneck, -odd under x8 PCI-E Lanes may compose 4 group of PCI-E the x1 connection, -odd next 4 PCI-E Lanes serves as with the south bridge transmission connection, is called ALink 2 Interface, only provides 2 PCI-E Lanes compared to former generation RD480 ALink the Interface frequency width promotion to reach 1 time.
Regarding nVidia already issued double x16 the SLi platform, ATi actually expressed it certainly cannot be true double x16 the SLi platform, according to William Tsao expressed RD580 double PCI-E the x16 cartography connection completely constructs by the northern bridge chip in, therefore between two piece of indicators material transmissions may complete in the chip, but nVidia double x16 SLi is south the penetration the bridge bridge respectively has group of PCI-E the x16 cartography connection to become, therefore between two piece of indicators like must penetrate the PCI-Express connection transmission, then needs to penetrate north its south bridge the transmission frequency to be wide, although the nVidia north and south bridge communication frequency width uses the superiority 16Bit 1GHz Hyper-Transport, But this transmission frequency width draws a chart the connection to monopolize by no means, in addition south the bridge supports many parts also simultaneously to take the frequency widely, has taken the partial frequency band and creates the nonessential detention (Latency), by no means true Dual x16 PCI-E perfect overhead construction, therefore only then met the partial test to appear double x16 also to want compared to double x8 the disappointing to be fearful phenomenon.
ATi expresses match C51D + CK804 by no means true double x16 the PCI-E platform, all because between the north and south bridge has made the bottleneck
CrossFire further will popularize
According to William Tsao indicated that, the ATi RD580 appearance certainly is not for substitute for former generation RD480, they will be able to coexist to the market (Some error in translator here) Taiwan fixes a price by $,150 US dollars to $,240 US dollars between, RD480 then will be able to enter the mainstream market to replace has not supported CrossFire RS480, the selling price by $70 US dollars to $,130 US dollars between, further will decrease the CrossFire platform threshold to hope ATi the double indicator coordination operation technology to speed up the popularization. In addition, a Taiwan merchant disclosed ATi will be able between RD580 and RD480, promotes the RD550 model again, it will be Pin to Pin compatible RD580, but its cartography connection will turn x16 + x8 by RD580 double x16, the merchant estimated this batch of RD550 will be the RD580 disappointment, temporarily will promote the date to be undecided.
