GeForce RTX 3070 Uses 14Gbps GDDR6 Memory: ZOTAC and ASUS

NVIDIA's upcoming GeForce RTX 3070 performance segment graphics card uses 14 Gbps GDDR6 memory speed, according to the product page of the ZOTAC RTX 3070 Twin Edge (model: ZT-A30700E-10P), and the RTX 3070 DUAL by ASUS. This settles speculation around NVIDIA using the fastest available 16 Gbps GDDR6 memory for the RTX 3070. The company is using the even faster 19.5 Gbps and 19 Gbps GDDR6X memory for the RTX 3090 and RTX 3080, which it co-developed with Micron Technology. The use of 14 Gbps GDDR6 across a 256-bit wide memory bus gives the RTX 3070 the same 448 GB/s memory bandwidth as the RTX 2070. NVIDIA plans to launch the GeForce RTX 3070 some time in October, with prices starting at USD $499.

kayjay010101USD? That's incredibly bad pricing. Even here in Norway, where things are jacked up the wazoo in terms of pricing; the 3070 starts at $642.
Some retailers in South-Africa are asking just under $800 for 2060 Supers. What a joke.

efikkanPrecisely what did Nvidia "gimp" on the GA104?
If this soundly beats RTX 2080 Ti despite potentially having significantly less memory bandwidth, then that's a impressive.

My concern would be that this card would be a little starved for memory bandwidth, but time will tell.


While RTX 3070 Ti isn't confirmed yet, there is a chance RTX 3070 will be using both GA104 and GA102 chips, like they have done in the past.
Whether it soundly beats the RTX 2080 Ti, it is too early to determine until we see reviews on it. My take is that it will win some, and lose some tests depending on game and settings. There are certainly more CUDA cores on the 3070, but they don't operate the same way on the 2080 Ti, so the increase may not translate to a near proportionate improvement. Most of the benchmark titles we have seen so far are heavily Nvidia optimized.

As to bandwidth starved, I believe the 3070 is able to provide very solid 1440p support and decent gaming experience at 4K especially with DLSS. At this resolution, I feel the bandwidth should be sufficient at least for the foreseeable future.
Hawkster222I saw local pricing in my country started to list the 3070 at 960$
This is a common issue for early adopters. Due to surge in demand and limited stock, prices will be inflated.

This is something many fail to understand, and is true for most architectural changes, and is also why we should be careful to estimate the performance of RDNA2 too. And as you were saying, it's very likely that any new architecture will improve some areas while getting worse(or relatively worse) in others as the resource balance is changed.

In order to optimize software for specific hardware, you need to design the software around special instructions, performance related features or specific performance characteristics.
Unless you count things like raytracing as an "optimization", there is virtually no recent game optimized for any specific architecture.

Bandwidth scaling varies a lot between games, it depends on how the games does LoD scaling, how many framebuffers and render passes are involved etc.
The GPU architecture also plays a role. The scheduling of operations and cache increases can have some impact.

kiriakostOne tip for Europeans looking for competitive pricing, for any VGA, they should keep track of the many German eshop.

Absolutely, very good advice, everyone considering buying PC parts should do this kind of thing.

At any point in time, I'm tracking various CPUs, GPUs, PSUs etc. that I'm considering for future builds or upgrades, and then I usually snap them up over time at great prices. One of the most fantastic things about PCs is the ability to do upgrades gradually, there is usually no need to pay for overpriced parts.
