Vendor Cards: MSI NX7800GTX

Final Words
The fact that our MSI card was able to overclock more than the EVGA doesn't actually matter. Performance of the two cards at maximum overclock is exactly the same due to NVIDIA's method of handling clock speed controls. With a little less heat and a little more noise, this card stacks up pretty well against our reference, but the EVGA's factory OC gives it a slight advantage going into the final round.What it really boils down to is price, and this changes constantly. Over time, you'll see the lower clocked 7800s selling for less, but since these cards are fairly new on the market, you can find some pretty good deals if you are lucky. The MSI NX7800 GTX is four dollars cheaper at ZipZoomFly than the $539 N538 version of EVGA's 7800 GTX (the version with a 450MHz clock and Battlefield 2). But the real deal (at the time of publication: 7/24/05) is Monarch Computer's sale of the EVGA N538 e-GeForce 7800 GTX for $500 ($507.70 including shipping charges).
Right now, our recommendation all comes down to price. The extra performance of the EVGA part out of the box is well worth another four dollars. But add Battlefield 2 and the lowest price that we've yet seen on a G70 based part to date, those interested should jump on this deal. The price of 7800 GTX cards will fall over time, but with many still selling at 20% more, this is definitely a deal.
We aren't sure how long this deal will last, but, as a general rule, for the same price (or even a couple of dollars more), the higher clocked version of the EVGA 7800s gets our recommendation. Pay attention to the part number here, as the name on the box is the same no matter which version is inside. Eventually, the lower clocked 7800 GTX cards may settle out to a lower price, and at that point, the choice will come down to the cost of an extra few fps and Battlefield 2 or Chronicles of Riddick. Riddick is an absolutely wonderful game (probably the best game based on a movie of all time), but Battlefield 2 is destined to be more popular (especially with those interested in buying a 7800 GTX).
That brings our second 7800 GTX vendor review to a close with the EVGA still on top. Please stay tuned as we continue to update price and performance numbers with more vendors' cards. Next on the list is BFG. We want to bring you the best and most reliable information around, and as more cards come along, we will continue to get a clearer idea of how each of the manufacturers implements the G70, and how they measure up to eachother. Please let us know if there is anything that we can add to this series to help make it the most useful 7800 resource around.

I'm not sure how board-specific this would be (although the BIOS could easily getin on the act), but I notice nVidia are claiming a big readback speed increase on
the Quadro FX4500 over the FX4400 (2.4GB/s vs 1GB/s). This doesn't seem to apply
to the 7800GTX in the GPUbench report I managed to find, but it's the kind of thing
which could be massively driver and BIOS-dependent.
I know this is a more artifical figure than the games which have been run, but
significant jumps like this (along with the increased vector dot rate) make these
cards much more attractive than the 6800 series for non-graphical work. Would it
be possible to try to confirm whether this speed-up is specific to the Quadro
board, or whether it applies to the consumer cards too? (Either by a little bit
of test code, or by running some artificial benchmarks.)
Just curious. Not that I'll be able to afford a 4500 anyway...

ALL 7800GTX cards at this point are manufactured by nvidia and sold as is by the "vendors". ONLY physical difference is the logo on the cooler. If some vendors screen and OC their cards before selling, clock speeds would be the only difference. ANY perfomance or heat dissipation differences at similar clock speeds are MERELY manufacturing variances.DerekWilson - Thursday, July 28, 2005 - link
Not true. Vendors have some bios control over aspect of the cards that are not exposed to users. We have not been able to confirm any details from any vendor or NVIDIA (as they like to keep this stuff under wraps), but temp, heat, and noise (and even overclockability) could be affected by video bios settings.We don't know the details; we need more clarification. In the meantime, these are the numbers we are seeing so we will report them. If we are able to get the information we need to really say why we see these differences then we will definitely publish our findings.

no matter how much better a card does im always going to by evga... ive saved more time and money with the step up program. there customer support is soo good too.NullSubroutine - Tuesday, July 26, 2005 - link
After reading an article about how CPU performance is tapering off (murphy's law or moores law, i forget which one), but GPU performance has continued to increase, and has showed signs that it will continue to increase. Also I remember an article about Nvidia or ATi (i cant remember which) was asked about any "dual core" GPU's that will be developed. They answered that if you really look at the hardware, GPUs are like multiprocessors, or something to that nature. Perhaps this could be the reason for the clockspeed questions? It would seem logical to me that their technology doesnt run like a typical cpu, because each "processor" runs at a different speed? I think you might understand what im trying to say, at least I hope so cuz im failing miserably at...what was i sayin?Gamingphreek - Monday, July 25, 2005 - link
Not sure if this has already been discussed in earlier articles, but, the 7800GTX as everyone (including myself) seems bottlenecked at every resolution except 16x12. And then with AA and AF enabled the X850XT seems to catch up. While the averages might be the same, has anandtech ever thought of including the minimum and maximum framerates on their graphs.Thanks,

Just wanted to thank Derek and Josh for clarifying the dual link situation. MSI don't mention anything about dual link, but after the debacle with their 6800"GT" I'm not sure I'd have trusted their publications anyway... If *all* the 7800GTXs are dual link, I'm more confident (although if there's actually a chance to try one with a 30" ACD or - preferably - a T221 DG5 in a future review I'd be even happier!)Good review, even if we can expect most cards to be pretty much clones of the reference design for now.

We'll have some tests with a Cinema Display at some point ...But for now, we can actually see the Silicon Image TMDS used for Dual-Link DVI under the HSF. :-)

Cool; it'd reassure me before I splash out! (Although I'm still hoping for the extra RAM pads to get filled out - got to hate 36MB frame buffers - but with the Quadro 4500 allegedly due at SIGGRAPH it shouldn't be long now.)Sounds like the same solution as the Quadro 3400/6800GTo, with the internal transmitter used for one link and the SiI part for the other. I don't suppose you've pulled the fan off to find out the part number?
I'd also be interested in knowing whether the signal quality has improved on the internal transmitter; nVidia have a bad record with this, and the T221 pushes the single link close to the 165MHz limit (and the dual link, for that matter). People have struggled with the 6800 series, even in Quadro form, where the internal transmitters have been in use. It'd be nice to find out if they're learning, although asking you to stick an oscilloscope on the output is a bit optimistic. :-) These days this probably affects people with (two) 1920x1200 panels as well as oddballs like me with DG5s, though.
On the subject of DVI, I don't suppose nVidia have HDCP support yet, do they? (Silicon Image do a part which can help out, or I believe it can be done in the driver.) It's really a Longhorn thing, but you never know...
Now, if only nVidia would produce an SLi SFR mode with horizontal spanning which didn't try to merge data down the SLi link, I'd be able to get two cards and actually play games on two inputs to the T221 (or two monitors); the way the 7800 benchmarks are going, 3840x2400 is going to be necessary to make anything fill rate limited in SLi. (Or have they done this already? There was talk about Quadros having dual-card OpenGL support, but I'm behind on nVidia drivers while my machine's in bits.)
Thanks for the info!
(Starts saving up...)

Nether Evga NOR MSI advertise that their card is capable of driving at the resolutions that would suggest that the dual-link DVI is enabled.E.g., MSI:
Advanced Display Functionality
• Dual integrated 400MHz RAMDACs for display resolutions up to and including 2048x1536 at 85Hz
• Dual DVO ports for interfacing to external TMDS transmitters and external TV encoders
• Full NVIDIA nView multi-display technology capability
Why would they conceal this feature/?
