Belangrijk moment in de Conference Call. De verkopen van Blackwell in Q4 komen bovenop de stijgende verkoop van Hopper. Het gaat dus niet ten koste van:
'Stacy Rasgon -- Analyst
Hi, guys. Thanks for taking my question. So, I have two short questions for Colette. The first several billion dollars of Blackwell revenue in Q4, is that additive? You said you expected Hopper demand to strengthen in the second half.
Does that mean Hopper strengthens Q3 to Q4 as well on top of Blackwell adding several billion dollars? And the second question on gross margins. If I have mid-70s for the year, let's say, where I want to draw that, if I have 75 for the year, I'd be something like 71 to 72 for Q4, somewhere in that range. Is that the kind of exit rate for gross margins that you're expecting? And how should we think about the drivers of gross margin evolution into next year as Blackwell ramps? And I mean, hopefully, I guess the yields and the inventory reserves and everything come up.

So, Stacy, let's first take your question that you had about Hopper and Blackwell. So, we believe our Hopper will continue to grow into the second half. We have many new products for Hopper, our existing products for Hopper that we believe will start continuing to ramp in the next quarters, including our Q3 and those new products moving to Q4. So, let's say, Hopper there for versus H1 is a growth opportunity for that.
Additionally, we have the Blackwell on top of that, and the Blackwell starting ramping in Q4. '
