ew toys arrive in the Lab as fre-
quently as political scandals erupt
in Washington, D.C., a phenom-
enon that renders the Maximum PC staff
a fickle, jaded bunch. But in the absence
of any competition from AT—er, AMD—we
remain intrigued by videocards based on
Nvidia’s 8800 series GPUs. And so this
month, we take a close look at EVGA’s
e-GeForce 8800 GTS.
The 8800 GTS is the less powerful of the
two DirectX 10 GPUs that Nvidia introduced
last November, but we need to put the
phrase “less powerful” in context because
both parts are based on the same G80 chip.
In other words, the 8800 GTS is basically
a hobbled 8800 GTX: It offers 96 shader
processors (floating-point units that Nvidia
refers to as “stream processors”), compared
to the GTX’s 128; 640MB of memory, com-
pared to the GTX’s 768MB frame buffer; a
320-bit memory interface, compared to the

GTX’s 384-bit inter-
face; and 20 raster-
izers, compared to
24 on the GTX.
The 8800 GTS
also runs at slower
clock speeds than
its pricier sibling:
The GPU on the
card EVGA sent
us was clocked at
513MHz, compared to 500MHz stock, but
the memory was ever-so-slightly under-
clocked at 792MHz, compared to 800MHz
stock. Compare these specs to the GTX’s
575MHz core and 800MHz memory. And if
you’re interested in dropping an HD-DVD
or Blu-ray drive into your rig, EVGA’s imple-
mentation includes the HDCP CryptoROM
that Nvidia’s NVIO chip needs to display
Hollywood movies at their full resolution.
The upside to the 8800 GTS’s down-
sized speeds and feeds is a significantly
lower price tag compared to cards based
on the 8800 GTX. At press time, the
e-GeForce 8800 GTS was selling for
$440 before taking a mail-in rebate into
account. The least-expensive 8800 GTX
board we could find, meanwhile, was
fetching a princely $610. But if you want
a videocard that’s capable of delivering
DirectX 10 and Shader Model 4.0, there’s
currently nothing cheaper than 8800 GTS-
based products.
If you’re willing to stick with DirectX 9
games—and who’s to argue, since currently
there aren’t any DX10 games—the dual-
GPU 7950 GX2 is significantly faster. But
it looks as though these cards
are not long for this Earth: We
found only three SKUs in stock
at New Egg as we were going to
press—and all three were priced
higher than cards based on the
8800 GTS. And, as with all of
Nvidia’s 7 series GPUs, the 7950
GX2 is incapable of performing
antialiasing and high-dynamic-
range lighting at the same time.
If you are willing to limit
yourself to DX9, on the other
hand, boards based on

AT—, ahem, AMD’s ATI Radeon X1950
XTX—also outperform the 8800 GTS.
These cards can do AA and HDR at the
same time, and some vendors are selling
them for less than 8800 GTS cards. But
it bears repeating that the X1950 XTX is
incompatible with DX10 and Shader Model
4.0, and then there’s the whole PITA fac-
tor of CrossFire and its external dongle
to consider, should you decide to build a
dual-GPU rig.
Returning to the matter at hand, the
e-GeForce 8800 GTS is no slouch: It
delivered Quake 4 scores of 65.5fps at
1920x1200 resolution, with 4x antialias-
ing and 16x anisotropic filtering enabled.
While that’s nearly 33fps slower than
the tonier 8800 GTX-based Asus card
we reviewed in January, running two of
EVGA’s cards in SLI boosted our Quake 4
benchmark to 111fps—12.6fps faster than
a single GTX. We obtained similar results
with our 3DMark06 , Company of Heroes ,
and FEAR benchmarks. The 8800 GTS is
a helluva GPU, but its DirectX 10 perfor-
mance—to paraphrase former Secretary
of Defense Donald Rumsfeld—remains an
unknowable unknown.

Expensive, and in the absence
of DX10, no one really knows
how fast it will actually be.

the prices for 8800 gts cards are creeping down, but the
absence of competition in terms of DirectX 10 compliance
continues to slow their descent.
