Fact 1) It says $351 not $317.
Fact 2) It says "Engine Clock: 880 MHz", so where did this 1.1-1.2GHz come from
So now $15 off coupon code on the front page and a $20 General MSI rebate don't count? Remove the MSI rebate and it's $332 still not $351. 7950 is like Q6600 / i5 2500k / i7 920 of the CPU world. It overclocks after 5 min of tinkering. Which is why people here bought a Q6600 G0 for $300 and not spent
$999 on the QX6850 or got the $284 i7 920 instead of the
$999 i7 975.
That's what we try to do here -- find a diamond CPU / GPU that has the potential to come close or even beat top parts. This saves us $ for future upgrades and rewards our research for picking quality parts that can actually achieve those characteristics.
For $20-30 more, 7950 has the potential to beat the $450-500 1000mhz 7970/680. 660Ti does not have this potential. For enthuasists, the 7950 is an underclocked enthusiast GPU and 660Ti is a real mid-range crippled GPU with gutted ROP/memory bus internals. One GPU can handle 8xMSAA and has 3GB VRAM for mods that doesn't cripple it in Skyrim, the other has to rely on FXAA to look good and at this point has 2GB of VRAM that may not even be used fully before crippling the memory bandwidth to 48GB/sec. The point is 7950 is like that i5-3570K CPU that can hit 4.5ghz and perform amazing while 660Ti is like an i5-3470 that performs about the same but has little left above that.
I know how you like graphs so here ya go one
Notice I said $207-220 HD7850 prices which is what you can find easily if you look. TPU uses MSRP only. Looking at market prices, 660Ti costs about 50% more than a 7850 and offers 34% more performance.
DISCLAIMER: Similarly like AMD, Techpowerup does not give free +400MHz boost to 7950 like you do. Call me unbelieving Thomas but if these cheap 7950/70 were built for those speeds you review them at, I am sure AMD would release them sooner or later, and certainly when GK104 halted their sales.
It's called yields. Just like NV launched GTX460 at 675mhz but many cards hit
850-925mhz. Yup, Fermi GTX460 was a smashing overclocking card and our forum members did take its overclocking capabilities into account when comparing it against the more expensive 5850 and later to the 6850/6870 cards. If you don't overclock your cards, then well this doesn't matter to you.
But AMD can not even guarantee 925MHz and recommends not to flash BIOS, and when flashed this is the real clock:
Yes and mentioned by every knowledgeable member of our forum you don't need to put 1.25V into a 7950. AMD did that to guarantee that all cards including those with 50% ASIC can reach 925mhz. What about MSI TF3 that's binned from the factory for 80%+ ASIC and hits 1100-1200 at or below 1.175V,
basically guaranteed? Not a single person on our board who actually bought that card wasn't able to get 1100mhz at 1.175V. I know it's hard for you to believe that AIBs would bin top 7950 chips and put them into Gigabyte Windforce 3x, Sapphire Dual-X 950mhz and MSI TwinFrozr while reference cards would get bottom of the barrel 7950 chips..... :sneaky:
There was/is that Toxic 7970, but it costs $700 and cca. 10 of them got sold before it went out of stock.
10 of them? I am not even going to ask where you got your facts.
HD7970 Vapor-X has the identical cooler from the TOXIC and 8 Black Diamond Chokes VRM from the TOXIC. At stock speeds it's faster than a $500 reference 680 and it overclocks to 1250mhz and can beat a 1290mhz 680 that costs more $. So why exactly are you bringing up the TOXIC? The reason I brought the MSI Lightning / EVGA Classy cards is because they are the only 2 GTX680 cards that can actually beat the Vapor-X. I am otherwise unaware of any other 680 that can hit 1350-1380 mhz on air without a volt mod.
TLDR Yeah I gather that 7950 OCs nicely. That's a great feature, and should be regarded as such.
Shall I regard them as 1200MHz GPU because forum guy has it such in his sig?
A 925mhz 7950 already beats 660Tis per 3DCenter's 12 reviews since 800mhz 7950 = GTX660Ti. You already linked to us that those GPU Boosted 7950s only get 5-6% performance increase since the GPU boost only works 50% of the time. That means the MSI TF3 880mhz or 900mhz Gigabyte Windforce 3x for $320-330 would beat a 660Ti using the same logic. I've never met a single after-market 7950 that couldn't get to 1000mhz period. If you choose to not overclock, like I said the 660Ti is a good card for non-overclockers.
While at it, did you ignore Athlon XP1700+ @ 2400+ speeds, Athlon XP 2500+ @ 3200+ speeds overclocking? Athlon X2 3800+ @ 4800+ speeds? Opteron 165 Overclocking? E6400 @ 3.2-3.4ghz, Q6600 @ 3.2-3.4ghz? Q9550 @ 3.8-4.0ghz, Core i7 920 @ 4.0ghz, Core i5 750 @ 3.8ghz, i5 2500k/2600k @ 4.5ghz, etc.
and on the NV side:
- GeForce 3 Ti 200 overclocked to GeForce 3 speeds
- GeForce 4 Ti 4200 overclocked to Ti 4600 speeds
- 6600 Non-GT had 50% overclocking headroom
- 6800 Non-Ultra unlocked into pipelines + Oced ~ 6800GT
- 7800/7950GT overclocking
- 8800GT's overclocking
- MSI TwinFrozr GTX260 216 could overclock to beat GTX275/280 easily
- Recent overclocking of 460/470 cards.
If we follow your advice, we should spend $300 for GTX660Ti and if we want more performance, we should spend $400 for a GTX670 and $500 if we wanted GTX680 level of performance? You know that's exact opposite of what we are trying to achieve here? We aren't aiming to make NV/AMD/Intel $$$ but we want to maximize the value per $ spent that an enthusiasts probably worked hard for to earn. If price/performance wasn't a factor, we'd be rocking Core i7 3960X + GTX690 SLI or similar. A lot of people try to maximize performance/$ and won't hesitate to download MSI Afterburner / EVGA Precision X and spend 5 min to get 20-40% more performance if it's possible to save $150-200 from buying top cards.
1170mhz HD7950 goes head-to-head against the OCed 1300mhz 670, which frankly makes the 660Ti look mid-range that it is.

If people considered saving $70-80 over the 670 to get a 7950 and overclock it, why wouldn't they spend $20-30 more over the 660Ti and get a way faster card in 5 minutes?
