More G80 features abound

As if we mere mortals needed more reasons to be excited about G80, here are a couple more tidbits: 128-bit high dynamic-range and antialiasing with 16X sampling.

The high dynamic-range (HDR) engine found in GeForce 7950 and Radeon series graphics cards is technically a 64-bit rendering.  This new HDR approach comes from a file format developed by Industrial Light and Magic (the LucasFilm guys).  In a nutshell, we will have 128-bit floating point HDR as soon as applications adopt code to use it. OpenEXR's features include:
  • Higher dynamic range and color precision than existing 8- and 10-bit image file formats.
  • Support for 16-bit floating-point, 32-bit floating-point, and 32-bit integer pixels. The 16-bit floating-point format, called "half", is compatible with the half data type in NVIDIA's Cg graphics language and is supported natively on their new GeForce FX and Quadro FX 3D graphics solutions.
  • Multiple lossless image compression algorithms. Some of the included codecs can achieve 2:1 lossless compression ratios on images with film grain.
  • Extensibility. New compression codecs and image types can easily be added by extending the C++ classes included in the OpenEXR software distribution. New image attributes (strings, vectors, integers, etc.) can be added to OpenEXR image headers without affecting backward compatibility with existing OpenEXR applications.
NVIDIA already has 16X AA available for SLI applications.  The GeForce 8800 will be the first card to feature 16X AA on a single GPU.  Previous generations of GeForce cards have only been able to support 8X antialiasing in single-card configurations.

This new 16X AA and 128-bit HDR will be part of another new engine, similar in spirit to PureVideo and the Quantum Effects engines also featured on G80.

One small leap for Nvidia one giant leap for gaming!

and one gigantic leap for your electric bill

Im not a tree hugger or anything like that but my current system pretty much makes up the majority of our $500 light bill here in Texas. Keep in mind, energy in Texas is relatively cheap.

Specs: X2 4200+@2500mhz, 2GB DDR500, 4 HDDs, overclocked 7900GT, 2 CRT monitors, and a 500watt power supply.

Im actually thinking about building a super engergy efficient computer next year. If I shave off $100 a month off that bill which I bet I could do, my family would have a bit more disposable income to play with. As much as I love the new stuff from Nvidia and ATI, they just suck way too much power. I hope Nvidia will have some energy saving features on this card.

You need to find out who has their search lights plugged into your house and disconnect them. A 500W power supply and two monitors (let's round everything up to 1KW) runs just about $800 *for the year* at $0.10 per KW hour.

And that's at full load, 24 hours a day, 365 days a year.

Hmm, I wonder how much power a triple-play setup of Xbox 360, PS3 and Wii would consume? Not like you'd be running all 3 at the same time though.

I am completely in awe and blown away at the specs of this chip though. 384-bit memory interface, 768MB of GDDR3 (or 4?), 128 unified shaders with Shader Model 4.0 and DirectXX goodness, etcetera etcetera ad infinitum. And to think this will likely launch (or at least be widely available) BEFORE PS3 even hits store shelves (and cost only a little bit more for GTX.) I guess all the PC gamers win this round??

I think he meant that the GTX version would be just a bit more expensive than the PS3.

my mistake - you're right, I stand corrected. GTX is slightly more expensive than PS3 but there's no Crysis for PS3 - fair enough :)

But still we need to include other PC component cost (RAM, CPU), and he's probably also miss out those hit titles in consoles.

Why does it not surprise me your from Texas?

First off.........$100 is not the majority part of $500. If you were to run your 500W system 24hrs a day your bill would be $36/mo (assuming .10/KWh). Not to mention the fact that you computer should go into standby mode, and under normal operating circumstances is taking less than 200W.

Even more power hungry would be the 2 CRT monitors. Although I'm sure that they also go into standby mode and consume less energy. Go LCD, but don't expect to save more than $5/mo for getting LCD's and a new energy efficient computer. Your dis-illusioning yourself if you think you'll get better gains.

The primary factors in an energy bill are always;
1. Air Conditioning/Heat Pump
2. Hot water heater (electric)
3. Clothes dryer (electric)
4. Oven/rangetop
and if your like my household.........too much 1500W hair dryer use.

To reduce your bill, invest (<--notice I did not say spend) for a new 16-18 SEER/12 HSPF heat pump (I'm assuming HP since that's Texas) and really save that $100/mo.

With reguards to the Nvidia card, I'm dissapointed that it takes so much power.

If that's a swipe at Texans or their intelligence, or maybe lack thereof, perhaps you should use YOU'RE, instead of your.

Why does every post that tries to combat the whiny "my computer gets hot!" posts get voted to oblivion? Admittedly, the swipe at Texans wasn't smart, but the rest of the post was worthy.

I run my X2 @ 2.6ghz system, 600w Seasonic S-12, which has the standard components, a pump for the water cooling loop, and an LCD (all fed through a UPS which probably introduces minor inefficiency) 24-7 and the impact on my Florida bill is actually quite negligible. And when I say 24-7, I mean full CPU load 24-7, non-stop. (Recently before a reboot after 29 days of up time, had 6 hours of idle time noted in task manager). And yet, a few months ago, the system was dead for a month, about 3wks of it, while I fooled with a busted motherboard. Did I notice a drop in my light bill? Nope.

Therefore, will anyone that can afford such a monster of a video card notice a significant swing in their bills? Very much doubt it..

It's a concern for laptops and SFF for energy drain and heat respectively, but for desktops? Give me a break.

Read more carefully. He never stated his computer caused $100 of his bill. He mentioned buying a new computer and SHAVING off $100 of his bill. Whether his statements are accurate is moot. My point is you should read and comprehend before you start criticizing people's posts.

Dude..i have 3 computers running in my house, plus EVERYTHING in my house is electric..AC/HP, stove, water heater, etc. I live in VA and my light bill is around $170/mo, plus or minus 10 bucks. my computers never go into standby, i usually leave lights on and the fan outside is always running. Seems to be like you're getting the shaft with no vaseline from your power company.

Electricity is like .16 cents a kw/h in texas. Include your heating bill in winter...

heating bill in winter isn't much different..we run the AC most of the time in the summer. I think we had a $300 electric bill once when we never turned the thing off. Why turn the PCs off? 2 desktops plus my server. Still not seeing how anyone has a $500 light bill with one PC.

Seriously. I have a C2D E6600 @ 3GHz, 2GB RAM, X1950XTX, 2 IDE drives, 4 120mm case fans, and 5 hard drives. At idle my system, including the 19" LCD monitor, cable modem, and router, uses around 240W through my UPS At max load my system uses 274W. My energy bill this month was $63 without much AC usage.

In a 3 bedroom 1100sq ft apartment in college, me and my two roommates in the summer only had a power bill of $250. Thats with 5 desktops(3 were high end gaming systems), 3 laptops, 3 TVs, speaker setups, AC, and lights. And that bill was only that high because the AC unit in that apartment was insanely inefficient.

Your computer maybe accounts for $10-15 of your energy bill a month.

I find that BS. I have a more powerful computer than yours (with more stuff in it with a 700w PSU (800w max) and my bill is nowhere near that amount. Texas = lots of AC. Try not having your AC on 24/7 :p There are definitely other factors in your statement.

Yah. I have a gaming Rig that only gets used for gaming, video editing, and stuff like that, and a much less powerful machine that gets used for web browsing, email, word proc. The big machine gets shut down alot. It can warm a rather large room ten degrees F higer in just a couple of hours.

And Yes, I'm from TX too. I have to run my AC 9 months out of the year, and if it's not run in the computer room it gets annoyingly hot unless it is winter and cold out. You have to factor cooling all that heat you make with the PC also, and the efficiency factor for cooling 500 watts with an A/C is low, so you are probably talking at ex. 0.5 factor another 1000 watts of a/c on top of 500 watts PC. I have no idea what the real efficiency factor is. But it does make running a PC in the south and southwest expensive.
