Japanese media has got a hold of the specifications table of AMD's Radeon HD 7800 series products, the HD 7870 and HD 7850. Hermitage Akihabara has not cited a source as such, so we assume it vouches for the accuracy of this table. The table reveals Radeon HD 7870 as having 1280 stream processors, a 256-bit wide memory bus width (derived from the memory bandwidth and clock speeds figures provided in the table), 80 TMUs, 32 ROPs, and clock speeds of 1.00 GHz core, with 1200 MHz (4.80 GHz effective) memory. This SKU has a typical board power of 175W.

The slide details the HD 7850 as having 1024 stream processors, 64 TMUs, 32 ROPs, the same 256-bit GDDR5 memory interface, with the same memory clock speed as the HD 7870, but with a lower core clock speed of 860 MHz. the board power for the HD 7850 is mentioned to be under 130W. Interestingly, 2 GB is standard memory amount for both cards. The Japanese site mentions the official launch date of HD 7800 series as being March 8, but also goes on to add that market availability (we're assuming they mean the Japanese market), is only expected on/after March 19.

I would had hoped for 1408 shaders for the 7870 :ohwell:
20% less shaders on 7850 thats a big difference.

Don't forget the differences between 40nm and 28nm.
And don't forget that GCN architecture is not the same as VLiW.

A stock 6850 has:
Pixel fillrate - 24.8Gpixel/s
Texture fillrate - 37.2GTexel/s

If the specs are correct, a stock 7850 has:
Pixel fillrate - +11%
Texture fillrate - +48%

vs stock 6870:
Pixel fillrate - -4.6%
Texture fillrate - +9.1%

So, a 7850 is basically a slightly improved and more efficient 6870.
It looks to me like they're positioning the 7850 to be in a 'bridge' position; with 2GB memory it falls into the mid-range sweet spot, with 1GB memory it fills the slot currently held by the 6790.
In terms of performance:
6770 -->6790 -->6850 -->6870 1GB -->6870 2GB
xxxx -->7750 -->7770 -->7850 1GB -->7850 2GB

no "reasonable" pricing until competitor will be releasing new similar card

amd made good product in time, and they deserves extra reward for this

Since the 7870 it's basically crossfired 7770's a corresponding price it's expected.

Well if that's the case, it will be overpriced again. The 7770 goes for 130 - 135€ right now, that'll put the 7870 at 260 - 270€. The problem is, for 280€, you can get a GTX 570 or a 6970, which will both rather clearly outperform the 7870. For it to be reasonably priced, I think it should be priced at 220 - 240€. In that case, it will cost the same as a 6950 2GB version, and it should also have similar performance, since the 7870 has less processing units, but higher clock speeds.

When do the mobile versions come out? Just thinking that if a 6850 was basically a 6990M, and it almost beat the GTX580M (or did beat it in some cases), then a 7850 should clean the clock of whatever rebrand naming system nVidia chooses to use for the GTX580M.

7850 will replace 6950, 7870 replace 6970. They will have similar performance with fewer shaders and lower power consumption.

You sound like a AMD marketing person... There is no way in hell the 7850 will match the 6950 in performance. (The same goes for 7870 vs. 6970)

HD 6950: Core clock: 800 MHz. Memory-clock: 1250 MHz. Stream processors: 1408. Computing power: 2.25 TFLOPS.

HD 7850: Core clock: 860 MHz. Memory-clock: 1200 MHz. Stream processors: 1024. Computing power: 1.76 TFLOPS.

What it will end up being I suspect is the same as what happened with Cape Verde (HD 77xx): same price, less performance and lower power consumption compared to previous gen cards. I'm hoping that the 7850 will be around 200€, and that the 7870 will be around 250€. However, I'm almost certain that the price will be higher than that.

Here, some benchmarks:

So, the 7870 si the new 6970 probably at the same price and the 7850 is the new 6950 proly at the same price.

It was expected that this new gen of cards, the 7800 series and under would bring the same performance for the same money as last gen.

The only reason to buy these cards is from someone coming from a 6850/6870/gtx560/460

Thanks for the link. I started from logical reasoning, there is confirmation.

According to these figures, the Radeon HD 7870 a few is pretty close to the Radeon HD 7950 and takes in most cases also pass the Radeon HD 6970 - as we had been using the hardware data was already expected. The Radeon HD 7850 Radeon HD 6950, however, appears between 6970 and rank, this is something even better than we had expected had been. So the performance gap between the Radeon HD 7850 & 7870 is lower, at least according to these few figures, 20 percent, as it would suggest the wide gap in the performance of 45 percent (albeit with identical memory bandwidth).

Those results make no sense to me. Not because how they fare against the HD6000 cards, but because of how close they are to HD7950. You're telling me that 700+ SPs (and related texture units) make almost no difference? Fake results or broken architecture? IMO fake. We'll see soon I guess.

difference is only suspect in BF3, and if there using OLD data for the 7950 from before the BF3 patch that would explain alot, the patch for 7000 series gave 7900 owners an extra 15% and a driver update added another 5-10% so keep that in mind, if there using old data on hand that would explain it,

other titles look about right

theres also the law of diminshing returns to keep in mind as welel

The HD7950 has 1792 shaders running at 800MHZ whereas the HD7870 has 1280 shaders running at 1000MHZ. The HD7870 has 512 less shaders(29% less) when compared to an HD7950 but is clocked 25% higher than an HD7950.

As far as I know 7870 has 1280 SP and as we see it's clocked at 1GHz while the 7950 has 1792 SP clocked at 800Mhz. We'll see.

It's 40% more shaders not 29%, and 25% higher closks so there is a difference, but I dunno you could be right.

But then, HD7850 is still too close and the number of SPs is even lower (-75% !!) and clocks not much higher. The difference just does not seem to correspond with the specs is all I'm saying. For how much will they sell them because if it's less than $380 they just made their own HD7950 almost obsolete.


And Wow! Those slides are hilarious. HD7870 41% faster than GTX570. Not even the HD7970 is so much faster. :laugh: Actual difference in W1zz's HD7970 review is 25-30%

You can think of the 7870 like double the specs of the 7770 so in crossfire reviews 7770 is on par with the GTX570 but.... ahhh, the pricing! I think they know by now what's to be expected from GK104 and the 450$ tag on the 7950 will last no more than one month. I think the 7870 will be at max 350$
