AGP bandwidth question
Hi,
I'm trying to find out about AGPx8 read and write performance. The "x8" means that write operations are 8 times faster than for AGPx1, correct? What about read operations? Are they always the same for AGPx2, AGPx4 and AGPx8? Is AGP a one way street? Any good link on the topic? Thanks you, Toni -- for mail, mirror: ed.lausivksa@elielb |

The "x8" means that write operations are 8 times faster than for AGPx1, correct? data transfer between different modes is ment IMHO in read mode from chipset to video card & rappresent only theorethical max bandwith, which is very very very rarely used (practically never, bandwith gets never satureted, mostly marketing!) there is practicaly no difference /real life, not benchmarks/ between speed of Agp2x and more /after 2x to 4x or to 8x there is only few % of improvement in benchmarks/. Speed of Agp transfer has nothing to do with slot/connecting standards directly; but different AGP X.x standards define different Agp voltage signaling to, so be carefuly which AGP slot of MoBo or Video card supports (check manuals!) What about read operations? Are they always the same for AGPx2, AGPx4 and AGPx8? Is AGP a one way street? IMHO is 2Way street, but sending data from video card to the rest of machine is way slower (write) than read in oposite way. (example: similar behavior like ADSL modems, upload is way slower than download) ... -- Regards, SPAJKY ® & visit my site @ http://www.spajky.vze.com "Tualatin OC-ed / BX-Slot1 / inaudible setup!"
