Anand has the details about r520,rv530,rv515
- Thread starter tEd
- Start date
I'm really puzzled by the memory specs for the rv530. The XT looks like it is 128 bit with 1400MHz effective GDDR3 memory and the Pro could be as low as 64bit with 800Mhz DDR1 memory.
One of those is either massively overendowed with bandwith, or one is massively underendowed IMO. I think probably the latter. Anand are right, the X1600Pro does look like a minefield to buy....

Because they're posting what they know up until this point before going under an NDA - which apparently will be tomorrow. From then on out the information we get from them will be in the form of formal reviews.

Why would they only go under NDA in the near future?
Pre-launch information blackout is my guess.
They (like other sites) will be receiving their card samples for testing in the coming days/weeks, and the NDA's are to make sure nothing with regard to the architecture, actual specs, or performance is revealed until the NDA's expire.

What's this about?
Richard Huddy's previous interview seems to make it a point to "hint" that RTT/HDR + AA is likely a capability, so perhaps there will be other new features beyond the pure technical specs that are meant to blow our skirts up here?
With or without benchmark numbers, I'm unable to be impressed without a set of features. Given just how damn CPU bound most modern games have become, I'm really becoming a much bigger afficianado of new features. RTT HDR + AA at decent framerates, as well as the new transparancy AA and mixed-mode AA forms are what's going to be the deciding factor for me. I'm waiting with baited breath to see what new "toys" the R5xx chipset might bring to the table moreso than framerates.

Well I have to say I'm impressed by the prices for the 512MB cards. I don't see how anyone can complain.
And relieved that this will finally put to rest all the 24 and 32 pipe nonsense.
So, the question remains - is 600MHz the top speed of R520 with the soft-ground problem, or with the soft-ground problem solved?
600MHz seems awfully low - although there have been hints before that 90nm was required for the process density more than speed.
Might ATI release an XTPE just in time for Christmas running at 700MHz?

You have this horserace, yes. People have been betting on a sure winner, but now this challenger is coming that's *exactly* as fast as the previous champion. Will people change their bets?Miksu said:
I hardly think so. Launching later than the competition you'll have to beat them outright to come out on top, and failing that create enough confusion as to who's really the fastest to keep the question open for debate. Achieving parity will put you in second place by default.

X1600XT is clocked on both core and memory the same as X1800XT, with half the memory bus width.
Does it seem reasonable to presume that X1600XT is an 8 ROP design
Presumably the memory chips on X1600XT are the same as those on X1800XT. Anandtech says that 512MB will be an option.
All of which implies that X1600XT will have a 4x32 memory interface, with the 512MB model having memory on the back of the board too
So with 4 memory controllers, and using quad ROPs, each of the two quad ROPs gets a pair of memory controllers

incurable said:Is it just me or is ATi once again throwing memory at a performance problem?
I guess I dont follow that statement. We know starting with the 512mb vers of the 800xl that these higher member cards were in the plan to show up someday soon. Maybe when the R520 and NVs 512mb card come your may have a few games that can use that extra memory (during the lifetime that you own those 512mb cards...like games based on Unreal Engine 3 should be showing up with on 6 months)....
