AGEIA, G80, ATI-AMD and other thoughts

Over the course of the last few days, I stumbled into the usual flood of speculation and details that didn't have a confirmed source.  As a general rule of thumb on DailyTech, we do not post articles on information that cannot be attributed to a source in writing -- but since we added a blog engine maybe it's time for me to express a few of the things I've heard.

During the show we saw some of our first NVIDIA slides with G80 information.  It's much too early to speculate about specifics of G80, but several vendors who have been reliable in the past have told me that G80 is a dual-core GPU with 48 pixels-per-cycle per core.  Given that the 90nm G71 is based on a design with a mere 24 pixels-per-cycle core, I am having a little bit of trouble swallowing this tall order.  The NVIDIA roadmap we've seen stretches into Q4'06, and does not have G80 on the map yet.  That's not to say G80 is not a 2006 component, but it's not on the roadmap yet as such.

Details of R600 were almost non-existent at Computex, even in rumor form.  We got our first look at a few slides that seemed to show R600 uses GDDR4, but this seems sort of a given considering vendors are already considering using GDDR4 on the R580 core.  As with G80, it's probably worth stressing that the ATI roadmap extends into Q4'06 and does not mention anything of R600.

The talk on everyone's tongue during Computex was the ATI-AMD prospective merger.  While I can't say I've seen evidence one way or another on this sort of deal, a few of my colleagues seem quite adamant on both sides of the fence.  Personally, I have a habit of not picking an opinion until I see it in writing. 

Conroe and AM2 also got their fair share of praises and slams accordingly.  Controversy still surrounds my former employer’s benchmarks of Conroe and Woodcrest, though I am reasonably confident the benchmarks at this time are starting to pan out in Conroe's favor.  However, the motherboards are still fairly immature and so far as I can tell no one has really been able to push the envelope with Conroe or Revision F outside of a few limited scenarios.

For all those AGEIA fans out there I have good news and bad news.  The good news is that PCIe versions of PhysX are on the way this year.  ASUS and BFG are the sole hardware providers in the US right now, but other tier 1 manufacturers have already confirmed to me that the exclusivity of ASUS and BFG will expire before the end of the year.  Now the bad news: it's still going to cost $280.  Engineers at all of the AGEIA partners seemed to hint that the PCI version of the PhysX card will come down in price at the time of the PCIe launch, but the results are conflicting as to whether or not AGEIA will adopt a new ASIC.

Computex had its showings of UMPCs and PMPs, as I had anticipated, but not nearly in the volume I had hoped.  I had almost certainly expected some surprise UMPC announcements, but for the most part the product managers I've dealt with wish to avoid the UMPC project like the plague... instead focusing on PMPs or tablet PCs instead. The majority of this animosity seems to revolve around battery life, as the device is too small to add a proper 6+ cell battery but also requires power hungry processors typically found in notebooks.  The Linux-based AMD alchemy devices from ECS were actually my most favorite, as the hack scene for such hardware is virtually unlimited.

Just to wrap up, I suppose I should mention HDCP -- considering virtually everyone on the show floor couldn't stop talking about it.  HDMI made a fairly strong appearance during the vendor showcases, which is great.  Almost every vendor is incorporating HDMI-to-DVI adaptors in with the HDMI-capable video cards at almost no additional cost.  I see this as a great move as the average RadioShack still charges $30+ for an adaptor.  The thing that puzzled me though was the number of HDMI-ready cards on the show floor that didn't support HDCP.  Granted, the HDCP certification is not cheap (Fudo claims its $15,000 -- which is true if you ship more than 10,000 units a year). 

I personally do not advocate DRM, particularly when it comes to HDCP, but I think the ship has already sailed with regard to getting TV manufacturers to stop implementation.  The adaptor manufacturers are certainly hesitant, but you can be sure if HDCP implementation was free to them we'd already have it in every PC and notebook.

Valid points, though I think the approach for quad sli isn't the best. instead of working on slapping another 7 GPUs into a system, i'd much rather have ATI do things like take r580 and fix the TMUs. i think they just dont have the resouces.

Ha Ha! Funniest thing I've read today! All pertinent points too.

It was ATI's design choice to focus on Shader Power at the expense of texturing power. The problem is that while texturing powers importance is diminishing over time, it's not going away over night. They bet the farm on shaders and for the moment the payoff is limited.

And compared to the 7900 GTX the X1900 XTX consumes 50% more power. Not surprising considering it has 107 million additional transistors. They have 38% more transistors, the wattage per transistor is higher on the ATI side.

Nvidia's balanced architecture is more favourable for now as it's performance is pretty predictable. With a 1:1 ratio for Pixel Shader to TMU's like legacy architectures of R300 and NV40.

A testement to Nvidia's driver team to be able to fix F.E.A.R performance, I am glad, now if they could do the same for vegetation in Oblivion I would be eqaully happy as they already have the performance crown indoors.

This generation is ATI's preparation generation as they threw on all kinds of things, HDR + AA, Ring Bus Memory Controller, better Dynamic Branching Performance, lots of Pixel Shaders. So next generation they don't have to do as much upgrading in those regards.

I would be really impressed if Nvidia did have 2x48 Pipes on the 2xG80 the die size of such a monster I can't even begin to imagine, as it would have to be upgrade to support DX10 functionality.

Yes, actually, it is.

Other wise retards like you would be doing it better.

While I don't doubt what Kris says he heard, doesn't 2x24, ala a dualcore G70, with some additions (GDDR4, HDR+AA,some way to handle DX10) make more sense?

That would seem to mesh more with how quickly they expected to be able to produce it back in the day when G70 was barely out the door. Obviously they've had problems, but it seems they were expecting some easily planned progression. It's very true things may have changed, and G80 is no longer the part they had originally planned, though, I suppose.

On 80 or 90nm, a chip like G70x2 that would seemingly be a logical step forward, as well as maintaining a die size approx. the same size as R580, if not smaller. A part like 48x2 though, even if it does not follow the same ratio ROPS, TMUs, and vertex shaders...That would still seemingly be one hell of a huge piece of silicon.

Na, it's actually mostly engineering. Computer, microelectronic, and electrical.

No propulsion systems at all, and no wind tunnel testing! ;-)

You are an idiot.... plain and simple. You really think ATI is that stupid and that video cards are that simple? You have a lot to learn. Never talk again by the way, you wasted 2 hours of your life with that stupid post.

Well that's just relative, isn't it?

You make it seem hard, the way i see those things is that it's nothing more than a few (ok a BUNCH, maybe even more than that (can you imagine :D)) mathematical equations.

And I don't believe ATI will ever fall, at least not this decennium.
