A 750ti is more efficient at stock, and faster overall once OC potential is factored in. This is a low volume part based off of ancient tech.

Hopefully there is more than this rebranded 7850 in the works.

What's the hash rate of a 7850 AKA 265X?

Someone on Reddit got a R7 265 and ran some tests. At stock clocks it was doing 327 KH/sec, and when increasing to a core clock of 1290 and memory clock of 1550, he was able to squeeze out 445 KH/sec. If these overclocks can be stably achieved on the majority of cards, that's a very good KH/$ ratio (nearly 3-to-1).

Much to the annoyance of some people here the 750Ti beating R7 265 has gone on sale for $149.
It promptly sold out.;)

Yup it looks like entire market is on fire.
A single SKU has been released, and at least several cards are already sold ^_^

But here is what's interesting. R7 265 has double memory bandwidth of 750 Ti, yet it barely catches up (when both cards OC-ed).
It takes BW-heavy Metro LL for 265 to finally take the lead, but again nothing to write home about.
What trickery is this? Isn't Nvidia supposed to be one with memory controller issue?

R7 265 is still very decent card for the money, and perf/$ $150 champ.
But between supply issues, availability, aggressive Nvidia Maxwell/750/Ti marketing, between old-vs-new tech and barely being faster than 750 Ti,
it's almost given that this card will sell in fraction of 750 Ti sales.
I mean NV is selling frigging Maxwell, and these guys can barely make a year 2012. Pitcairn.
Without accusing Chinese New Year for their supply woes. Like Chinese New Year is some rare and unpredictable natural catastrophe, and not same-time-every-year holiday.

Is 1290 a common stable overclock for a 7850 AKA 265?

Not really for a 7850

1200 would be more common.

I was able to run my Asus 7850 @ 1310 back in the day but the fans basically ran 100% and were too loud. (plus more voltage needed than I liked)


1150-1250 was common core range

Keep in mind that dedicated miners will usually be running their cards in an open-air frame, on powered risers, with a box fan blowing at the heatsinks. And they don't care about noise levels either (since these rigs are usually shoved in the basement or garage). Also, it's likely that the maturity of the TSMC 28nm process will enable higher overclocks and/or lower fan speeds and voltages than was the case for the first wave of Pitcairns in mid-2012.

Well 750ti wins on power hands down. And 265 wins on performance hands down.
I prefer getting better performance. This is just like 7790 vs 650TI boost.

The most I was able to get out one of the two 7850s that I have was 1250 core clock. Haven't played around with the memory that much since there were no yields after 1300.

The highest hashrate I obtained was about 430 or 440 but the card ran too hot and unstable. At 1200/1300, I get 420 hashes 24/7 on my powercolor 7850 2GB.

I think you might want to take another look at the 750ti reviews because I can't find a single one that says "faster overall". I can't find a single one that even says it's faster in anything. Please link me to where it says "faster overall".



R7 265 unlocks to a full 7870 and performs roughly 50% faster when fully unlocked, but you don't need to do that because it's already faster when not unlocked, runs cooler, and costs the same. It also has a much higher hash rate. But if you're sweating electricity and hate performance the 750ti might be the solution.

I doubt that. The 265 is 20% faster overall according to AT, and it's known to scale 30% (900 > 1200 MHZ) when overclocking. The 750Ti would need to overclock 56% to catch up... and scale with that overclock too (I'm skeptical it will with that 128bit anchor its got attached)

Maybe you've seen otherwise? If so, please share...

All the benchmarks I've seen also show that the 265 is faster at stock than the 750Ti. It's also easily capable of getting 100kH/s more than the 750Ti.

If the R7 265 unlocks to a full 270, and a 270 is a revamped 7870. Most 270s can reach much higher OCs than 7870s. However, I simply do not see how a 265 can run cooler than a 750Ti since the 750Ti uses about 40% less power and some 750Ti's use much more powerful coolers than they need.

Edit: Found this one of the newegg reviews of the Sapphire 265:
This card is fused at the hardware level - it cannot be unlocked with a softmod BIOS update... All four R7 265's had their substrate physically cut.

That is coming from the same guy who could not get higher than 160kH/s from any of his four cards... so I wouldn't take it too seriously, but it is something to consider.

I clicked 4 of the benchmark pages, and it won two, but lost GRID and one other one.

It trades blows, yet:
