AMD's New Radeon HD 7950 Tested
MojoKid writes "When AMD announced the high-end Radeon HD 7970, a lower cost Radeon HD 7950 based on the same GPU was planned to arrive a few weeks later. The GPU, which is based on AMD's new architecture dubbed Graphics Core Next, is manufactured using TSMC's 28nm process and features a whopping 4.31 billion transistors. In its full configuration, found on the Radeon HD 7970, the Tahiti GPU sports 2,048 stream processors with 128 texture units and 32 ROPs. On the Radeon HD 7950, however, a few segments of the GPU have been disabled, resulting in a total of 1,792 active stream processors, with 112 texture units and 32 ROPs. The Radeon HD 7950 is also clocked somewhat lower at 800MHz, although AMD has claimed the cards are highly overclockable. Performance-wise, though the card isn't AMD's fastest, pricing is more palatable and the new card actually beats NVIDIA's high-end GeForce GTX 580 by just a hair."
Welcome to 2005. Yawn.
What's the calculations per watt? Will I be able to put them in a crossfire frankenbox to make my fortune?
So when will there be cards affordable by normal people? Also for me the biggest thing to come out of the new design is that we should be able to get a passively cooled card with more performance than the HD5750.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
"a few segments of the GPU have been disabled"
As in, can be re-enabled with a custom BIOS or something?
But does it run Linux?
No, seriously... last time I tried to install Ubuntu with an ATI card (a few months ago), I couldn't get dual monitors to work correctly.
The restricted drivers exist, but are unstable, awkward and painful. Linux and Nvidia - a bit better in my experience..
When Nvidia puts out a $500 card, it's attractively priced.
When AMD puts out a faster card for 10% less, it draws complaints about the price from the same reviewer. What gives?
I have a low-end AMD card running 3 monitors right in front of me (Radeon HD 3450) . Must've been user error. ;)
I kid I kid... =P It was actually a huge PITA to set up 3 monitors, but before that I had been running two monitors very nicely for a very long time. It's incredibly easy in my opinion.
This is the card I used for the 3 monitors: http://www.jaton.com/VGA/graphics_card_detail.php?pid=138
...well, let's clear things up: I was always an AMD fan. Their CPUs rocked. I had a seriously great time overclocking my SS7 gear until it boiled.
The graphics cards sucked though. I'm talking about the old Radeon AGP cards. Put down your paddles, lads, 2006 was the last time I bought an ATI branded card (an X1800) and IMHO it sucked monkey balls. I couldn't even get it to perform at low resolution on Unreal 2002. That's why I went straight back to the store and swapped it for an NVidia 7600GT. Oh, yeah, life was sweet after that.
A couple weeks ago I bought a secondhand Sapphire HD3650 with 512MB DDR2. OK, it's a bloody old and very low spec card by tech standards, but it blows my GF 7600GT right out of the water - even on a slower, single core 64-bit processor running 32-bit platform. That made me a fan of ATI/AMD graphics right there. The old machine (Core Duo) with the NVidia is now collecting dust.
Operation Guillotine is in effect.
numbers. The loss racist? How is FreeBSD went out another charnel despite the from w1thin. perform keeping obsessed - give a sad world. At
im on a 6950, it is clocked at 810 mhz, but it can do 910 mhz by just using the ati catalyst slider. no fancy stuff. if you go into serious overclocking, you can approach 1000 mhz easily, if you play with the voltages and stuff.
moreover, X950s are generally unlockable. for example i unlocked the 6950 im sitting on, unlocking 24-30 or so shaders, basically making it a 6950. i could also flash a 6970 bios and make it a full 6970, but that's totally unnecessary, since i can get more than that by overclocking.
a good deal.

"Beats NVIDIA's high-end GeForce GTX 580 by just a hair."
You don't say. Must not have factored in Nvidia's history of selling and shipping GPUs that were known to be defective and then conspiring with the purchasers to hide this fact from the users until after their warranties ran out.
If they had, this new GPU would out perform Nvidia's by huge leaps and bounds.
6150 Go. Look it up.
In the interest of fairness, I'd also like to point out that the 580 still costs more than the faster 7950. And yet the reviewer still gripes.
My dick won't get hard until video cards take up 4 expansion slots and require 2 kW power supplies. Shiiiiiiiiiiiit.
If you find this post offensive, don't read it! THINK ABOUT YOUR BREATHING! I am what I am because of how apes behave.
really what is the point of this any more? 90+ % of your games are optimised for consoles first giving you at best a geforce8800GT, computer monitors are not getting any higher resolution and they still have not come up with a cooling system that doesnt clog with dust in a month!
nevermind the absolute shit drivers ati ships
I won't buy an ATI card until the Linux driver situation is fixed.
The last ATI card I bought was an HD5970 shortly after it was released. The card worked... fairly well... Performance on some games was pretty good but others were full of artifacts and/or crashed outright. Various driver releases alleviated some problems but not nearly all of them. Most problems required some "creative" solutions on my part to get my programs to work correctly. After finally getting fed up with the whole situation, I finally caved in and bought an NVidia card. Performance increased and I never had any problems with it. As long as both card companies stay roughly on par, I'll stick with NVidia.
Take any shooter or MMO with really large maps and corresponding memory requirements.
For instance, "All Points Bulletin" comes to mind. After a few minutes, it always brought my PC (AMD dual core, 2GByte RAM, NVidia 8600 GT) to its knees due to requiring 2GByte of memory or more for itself.
CPU and GPU seemed to have no problem, as the game ran fine until the memory limitation kicked in. So I guess the CPU and GPU in current-gen consoles might be able to handle the load as well. But memory-wise, they would run into problems even sooner.
C - the footgun of programming languages
So far, 3D acceleration is also significantly slower than in the closed sorce Catalyst driver. Some of that technology may also be owned by 3rd parties, but it is not as clear-cut as in the case of HDCP.
I suspect AMD's reasons for not releasing that stuff are part legal and part not wanting to give away the latest know-how.
But the latter seems a bit silly, as NVidia drivers already have the better reputation and probably the better code. AMDs advantage seems to be on the hardware side, with their chips cranking out more (theoretical) GFlops/watt.

5 years of GPU development hasn't been nearly enough; this thing still gets like 20 fps in Crysis.
Which APU platform is this a part of?
I know my basement isn't that clean - I hardly sweep my office room; but clogging with dust in a month? Holy hell.
