760 from 560-448 experiences?

Guest
I am trying to convince myself I just made a good purchase. Bought the EVGA 760 (twin fan...no more single fan for me) for $260 from Amazon.

I currently have a gtx 560 ti 448 (evga ftw edition). This card's fan really whines and drives me insane.

I looked at the history of 670 pricing and it took months for it to lower in price. So I am hoping the $260 price for the overclocked model will probably hang around for more than a month before dropping to sub-$220.

Has anyone else made this upgrade? Most reviews I have seen dont compare to the gtx 5XX series, much less the core 448 limited edition gpu.

I game at 1440p and have a 4.5 GHz i7-2600k for reference. Bioshock Infinite stutters a lot for me. Also, GW2 with max settings and windowed mode is kind of sluggish. I am hoping the 760 with smooth those out nicely. I kept thinking about waiting for the 770 price drop, but I am HOPING the 760 is what I am looking for (I usually go for the mid-range).

Has anyone else made a similar upgrade and had a good experience?
 
1440P I would pick a radeon 7950 3gb over a 2gb gtx760 since the price is very similar. 2gb ram should be enough for 1080p, but 3gb is better for 1440p.
 
OP: Hope all works out well with your purchase.

I am in a similar boat where I am waiting for my 1440p monitor to arrive. I think the monitor is going to remind me just how old my HD5770 card is. I was initially looking at the 760, but the cards I wanted (Msi twin frozr, Evga ACX cooler) were out of stock at Newegg and Amazon. I have not seen the 7950s in the $250 price range and would like to know the spread you are considering as "similar" or if I am just shopping the wrong places.

I do have a slight AMD bias, still rocking a 1090t until I can justify a Haswell/Ivy upgrade, but it looks like at the $250 pricepoint, the 760 makes a convincing argument.

Try to convince me otherwise, my budget is a bit flexible, what with shipping costs, but don't try and tell me anything more than a $25 difference, shipped, is close.

TL;DR:
CPU: 1090t@3.2-3.8GHz (seasonal)
RAM: 8GB@ PC3-10600(+)
GPU: Radeon HD5770 (This is the part I am looking to upgrade
Mon: Monoprice IPS, 2560x1440
SSD: Vertex 2 120GB
PSU: TBD (was thinking 520w, my 650 was overkill and now sold)

2GB is fine for 1440p with a single card.

3GB for 1440p is better if plans to Crossfire. If not, 2GB is fine.

@ ~$250 the 760 is a great card. Especially considering the price of the 670. It's probably about as fast as if you SLI'd your 560ti 448. Unlike some though, I do believe that the 3gig of vram that the 7950 has could be beneficial at your resolution. Especially if you tend to skip a generation again before upgrading.

Well, it's after a $20 rebate, but here's a dual fan Sapphire for $250 on Newegg.

I don't know how similar the 670 is to the 760, but I went from a 560ti 448 to a 670oc on a 1440p monitor and noticed a good difference. Would I do it again? Maybe, maybe not. I think if I could go back in time, I'd drop back to a 1080p monitor as I don't see a huge difference there. I'd have saved money all around.
 
7950 non boost is probably 15% faster than your stock 448, maybe a bit more at 1440p.

It won't have the frame buffer issue you're talking about, but performance isn't going to knock your socks off at stock, if you overclock you should gain a fair bit over a 448 OC (presumably you can hit 900-950 core).

This gen has been pretty "Meh", avoid crossfire it's currently broken in a lot of titles.

IMO, just drop your texture setting a notch or two when you run into frame buffer issues like in BioShock, drop AA or Shadows/AO in GW2 you shouldn't lose much in the way of IQ and get good fluid play.

Pass this gen, it's been pretty trash. Wait for 20nm, hope for better competition for better prices.

you are TRYING YOUR BEST to downplay the HD 7950 as an upgrade. firstly the HD 7950 boost is the more widely available product with average overclocks in the 1100 - 1150 mhz range.

http://www.techpowerup.com/reviews/HIS/HD_7950_X2_Boost/28.html

2560 x 1600

GTX 570 - 68
GTX 580 - 78
HD 7950 iceq x2 boost - 100
HD 7970 Ghz - 116

HD 7950 boost at average overclocks of 1100 - 1125 mhz matches HD 7970 Ghz. a 900 mhz overclocked GTX 560 Ti 448 barely matches a stock GTX 580.

http://hexus.net/tech/reviews/graphics/36565-evga-geforce-gtx-560-ti-448-classified/?page=12

so a 1100 - 1125 mhz HD 7950 is 50% faster (78 x 1.5 = 117) than a 900 mhz GTX 560 Ti 448. thats not insignificant. 🙄

http://www.newegg.com/Product/Produc...82E16814202026
http://www.superbiiz.com/detail.php?name=AT-79503GB

for USD 270 (without games) and usd 284 (with 4 free games) this card is definitely a good upgrade. after selling the GTX 560 Ti 448 for USD 100 - 120 , the upgrade costs USD 150 - 170. for 50% better performance thats a very reasonable price.

Why for the last year you keep talking about 800mhz 7950s and still keep talking about it when 925mhz 7950s are $250? 🙄

Here we go, making up facts again on the performance. GTX560 Ti 448 < GTX570.

perfrel_2560.gif


That means a $250 7950 is at least 47% faster than a stock 560Ti 448 at high rez.

HD7950 overclock > GTX680/7970GE:
http://www.legionhardware.com/artic...z_edition_7950_iceq_xsup2_boost_clock,13.html

An overclocked 560 Ti 448 can't even touch a GTX580 due to a VRAM bottleneck at 1440P. How much faster is HD7970GE vs. a GTX580 at 1440p/1600p in TPU's chart above? 49% That means HD7950 OC will be at least 50% faster than an overclocked 560Ti 448. It's going to be much more though since 1.28GB of VRAM is not enough for modern gaming at 1440P which means that 560Ti 448 OC is going to be much closer in performance to the 570, not the 580.

Right, HD7970 OC outperforming GTX580 OC by 50-60%, GTX760 outperforming GTX580 for half the price:

GTX780 after-market cards beating GTX580 by 89% at 1600P:
http://tpucdn.com/reviews/EVGA/GTX_780_SC_ACX_Cooler/images/perfrel_2560.gif

AMD cards paying for themselves with BTC.

Your favourite Fermi generation is getting owned hard in latest games like COH2. $500 MSRP GTX480 is more than 2x slower than a $370 HD7970 1Ghz. That means in some titles an HD7950 OC would outperform a GTX480 OC by ~ 2x for only $250!!!

No, just stating that it's not a large one.

Your review is old, and 1600p isn't 1440p, the disadvantage of the 448s lower bandwidth is found somewhere between 1080p and 1600p for his res.

At 900 it should be pretty much even with the 580, at 950 it should be pretty close to the 800MHz 7950.

perfrel_1920.gif
perfrel_2560.gif


So probably around 40% faster than a decent 448, this is of course assuming he overclocks. Less if he doesn't.

It's not insignificant, I don't think that word was used until you used it. However it is rather pathetic, considering the 448 is basically a 470 and there is nearly a two year separation between the two cards in question and a full node shrink, plus overclock just to start talking about 40-50% faster. That is lackluster imo, but I wouldn't talk about significance, that's for the OP to decide. The difference 40-50% gives you is the difference between a couple settings.

My thought is hold, wait for 20nm, or at least a refresh from AMD. The 7950 isn't getting any faster, and it isn't going to get any more expensive either. GTX 780 is really the card you want, it's just priced at ridiculous levels due to a lack of competing products from AMD currently.

i think if you have a 30 to 40% overclock on the 7950 it has no choice but to be 50% faster than it. That would also make the stock figures not so far off from where balla has stated (7950 non boost). You are arguing over a few points here or there. But, I do believe a 900mhz 560 448core would be rather close to the gtx580 in performance- at least around 1080.

The biggest plus to a 7950 is the 3gb frame buffer. This would be especially great for higher resolutions. But what i am wondering is why we are even talking about the 7950 at all? The OP already went from a 560 448 core to a gtx 760.

OP, i would love to see your thoughts once your card comes in. There is nothing better than first hand experiences.

stock for stock the HD 7950 iceq x2 boost (950 mhz) is 47% faster (68 x 1.47 = 99.6) than GTX 570 according to tpu review at 1600p. GTX 560 Ti 448 would be comfortably more than 50% slower than HD 7950 boost(925 mhz). so even at stock the diff is > 50%. you don't need to overclock to see the perf benefits.

so do you realistically expect the GTX 780 to end up at USD 300 when the HD 9970 launches. atmost you can expect a USD 150 - 200 price correction. AMD is not going to enter a price war especially when they have a very competitive product.

Balla said HD7950 is 15% faster but real world benchmarks show 47%. I think you read his 15% as 50% in your head. 😛

Click to expand...

But the context in question is 1440P, not 1080P. Also, no point in comparing a 900mhz 560 448 to an 800mhz 7950 when 925mhz 7950s are $250 and 7950 overclocks another 20-30%, negating any overclock the 560 has. In other words, without a VRAM bottleneck, stock vs. stock or OC vs. OC, the 7950 on average is going to be ~ 50% faster at 1440P.

But what i am wondering is why we are even talking about the 7950 at all? The OP already went from a 560 448 core to a gtx 760.
Click to expand...

Because the 760 and 7950 are very similar in performance which means talking about one or the other is nearly interchangeable. Balla said the upgrade is too minor but 50% is not minor if the OP sell his 560 to offset the cost of his 760 upgrade.

http://www.computerbase.de/artikel/grafikkarten/2013/nvidia-geforce-gtx-760-im-test/4/

For example if he sells his 560 448 for $120, then his net upgrade cost is $130 for a 50% gain in performance. NV is asking $150 for a 20-25% increase in performance to step up from 760 to 770. Therefore, the OP's upgrade is actually a very good deal. I would take a 50% gain in performance for $130 net all day and increase in VRAM to 2GB for future games. 😉

Did 560 448 magically gain more performance since that time? Nope. 7950 925mhz is 47% faster on average stock vs. stock. If anything, 560 448 looks even worse now after games like GRID 2, Dark, COH2 have come out that hammer Fermi cards.

read this post. Both the OP and the above poster talked of 1440p. balla saying a stock HD 7950 at 800 mhz is 15% faster than stock GTX 560 Ti 448 was completely wrong. the HD 7950(800 mhz) is 10 - 15% faster than a stock GTX 580 at 1440p / 1600p. moreover talking about HD 7950 at 800 mhz was completely irrelevant with the HD 7950 boost cards clocking at 925 - 1000 mhz out of the box.

here is the gigabyte HD 7950 OC which runs at 1000 mhz with the boost BIOS (in fact the last user review confirms the same)

http://www.newegg.com/Product/Produc...82E16814125414

this card selling for USD 280 at stock speeds beat a stock GTX 570 by > 50%.

how does it matter when the review was done. HD 7950 boost(925 mhz) is 5% slower than HD 7970(925 mhz). you just need to make sure the HD 7950 card is not clock throttled by 0% power control. its well known that HD 7950 at 975 - 1000 mhz matches HD 7970(925 Mhz) and at 1100 - 1125 mhz matches HD 7970 Ghz.

Stock? They're pretty close, though I'd give the nod to the 7950. OC vs OC 7950 gains a bit more performance, more akin to 670/680, top cards closer to 770 OC.
Click to expand...

HD 7950 OC(1.15 Ghz) beats a GTX 760 OC(1.3 Ghz) in games like Metro Last Light, crysis 3, farcry 3. but in few GE games like Tomb raider or Hitman the HD 7950 OC(1.15 ghz) beats GTX 760 OC(1.3 ghz) by > 20%. and thats at 1080p. at 1440p its going to be even more in favour of HD 7950 OC.

GTX560Ti 448 is only 16% faster than GTX560 Ti. In modern games, HD7950 V2 and GTX760 mop the floor with it.

http://images.anandtech.com/graphs/graph7103/55825.png
http://images.anandtech.com/graphs/graph7103/55838.png

http://images.anandtech.com/graphs/graph7103/55814.png
http://images.anandtech.com/graphs/graph7103/55819.png

If we compare minimum frame rates in particular, this is a very big upgrade:
http://www.anandtech.com/show/7103/nvidia-geforce-gtx-760-review/4

In comparison going from GTX275 to GTX470 was 42% faster at 1080P 4AA and 1600P.

Let's not forget that GTX760 brought GTX670 level of performance for $250 about 1 year after the 670 launched. The OP can now wait 2 more years and just pick up a GTX960 for $250 could provide GTX870 $400 level of performance. Why would next generation 20nm cards be cheap when wafers on lower nodes are becoming more expensive and GPU makers are passing those costs to early adopters? It's highly unlikely that we would see 20nm GPUs until Spring 2014. In that time the OP will have enjoyed a 50% increase in performance for a minimal cash outlay after selling his 560.

Did 560 448 magically gain more performance since that time? Nope. 7950 925mhz is 47% faster on average stock vs. stock. If anything, 560 448 looks even worse now after games like GRID 2, Dark, COH2 have come out that hammer Fermi cards.

Yes, actually it did since driver updates for Kepler continue to boost Fermi performance.

Maybe I was a bit off on 560 448 > 570 > 580 performance, still looking at 580 > 800MHz 7950 it's only about 5% faster.

925 is a 15% overclock, I wouldn't really call it stock I'd call it factory overclocked.

Either way, a setting or two and you're fine. No reason to toss money at such a modest gain so late in the generation imo of course.

According to hwbot the avg OC for a 7950 on air is 1147/1626MHZ roughly a 43% clock speed gain, probably a 40% performance gain over 800MHz, 560 Ti on the other hand averages 922/1603MHZ on air, which should put it ahead of the 580.

Thus without cherry picking games or using false premise clock speeds like other posters, 40% was born.


OP sorry for the derail, I hope you enjoy your new card and higher IQ!

Look at the benchmarks I linked. GTX560Ti is getting creamed in latest titles in the 760 review. Its performance has gotten worse since games got even more demanding.

So you inflate GTX560Ti 448's performance to 580's level and downgrade HD7950's performance to 800mhz level? Way to go.

This argument is nuts. It's like saying GeForce 4600 is a 4200 overclocked, 5950 Ultra is a 5900XT overclocked, 6800 Ultra is a 6800GT overclocked, GTX560 is a GTX460 overclocked, 770 is a 680 overclocked, etc.

HD7950 V2 might as well be called HD7960. 925mhz 7950s are going for $250. There is no point at all talking about 800mhz 7950s but you keep doing it. :hmm:

This is the perfect time to upgrade before his 560 Ti 448 loses even more value and before even more games bring his VRAM bottleneck out. He can then hold out another 2 years before 20nm cards are affordable. You think AMD and NV will sell you 20nm high-end cards for $250-350? Not a chance. Look at the benchmarks @ AT's review of GTX760 I linked. The 760 is crushing the GTX560Ti. They difference is far larger than between Titan and 7970GE.

Thread is dead no reason to continue this... Either way here is how I came to my 40% conclusion, take from it what you will RS.
