AMD Radeon RX 7600 Final Specs and Power Figures Leaked, Uses 6 nm
Here are the final specifications of the Radeon RX 7600 RDNA3 graphics card, bound for launch later this month. The specs list springs up some surprises. To begin with, while the GPU at the heart of the RX 7600 is based on the latest RDNA3 graphics architecture, it is built on the older 6 nm (DUV) silicon fabrication process—the same one on which the previous "Navi 24" was based. The silicon has a transistor count of 13.3 billion, about 2 billion more than the 7 nm "Navi 23" Powering the RX 6600 series, but a die-size of 204 mm². The GPU has a PCI-Express 4.0 x8 host interface, and a 128-bit GDDR6 memory interface. As the RX 7600, it has a TBP (total board power) value of 165 W, which is over 30 W more than the RX 6600.
At this point, it's not known whether the RX 7600 maxes out the silicon it is based on. It gets 32 RDNA3 compute units (CU), which work out to 2,048 stream processors (with the same dual-issue instruction rate feature as the RX 7900 series); 32 Ray Accelerators, and 64 AI Accelerators. The GPU has 128 TMUs, and 64 ROPs. The GPU has 32 MB of second-generation Infinity Cache memory. The 8 GB of GDDR6 memory ticks at 18 Gbps, which over the 128-bit memory bus works out to 288 GB/s of memory bandwidth. AMD claims that when coupled with the on-die cache, the "effective bandwidth" is 476.9 GB/s. NVIDIA is putting out similar "effective" figures for its RTX 4060 series, so this could become a norm. The RX 7600 comes with a game frequency of 2250 MHz, and 2625 MHz boost. AMD is making 550 W as its PSU recommendation, compared to the 450 W it did for the RX 6600. The company considers the RX 7600 to be the logical successor of the RX 6600 (and neither the RX 6600 XT nor the RX 6650 XT).

Anyway, please for the love of RTG don't price this at $300, get crushed by 4060 on day 1 review, then reduce price bit by bit in following months.
Just release it at $250 and finally compete, please?
Yeah, more vram is better but again it will drive up the cost. Idk what the price of this card but if it cost > $300, 6700XT is a sweeter deal than this.
Caches weren't invented yesterday; is the 7800X3D also supposed to use its V-cache to pump up its "effective" DDR5 bandwidth? :shadedshu:
New arch + (slightly) smaller node = ~30% higher board power o_O
One can only hope perf/W scales linearly as well
I doubt it will happen on the fps charts but I'm very willing to be wrong.
"Is this what we where building for 2 years? Is there any real difference over RDNA2?"
Navi 31 reduced the amount of L3 cache while doubling the bandwidth per cell, which is why they increased effective bandwidth contribution from the L3 despite lowering the cache from 128 to 96MB.
In the case of Navi 33, the only bandwidth increase seems to be from chancing GDDR6 14Gbps to 18Gbps. A difference of 4Gbps does 64GB/s at 128bit, which is the bandwidth difference between Navi 33 and Navi 23 according to that table.This card is dead in the water if AMD tries to charge anywhere near 300€. Even if they try to charge something like $280 people will just prefer to pay more for the 4060 as no reviewer or influencer is ever going to advise its purchase.
This needed to be 230€ to get major recommendations and it would set the world on fire at 200€. Which is probably where it will end up being priced at anyway, by the end of the year.
It all depends on whether AMD is willing to price it right or they're willing to risk massive pushbacks and disappointment from consumers.IIRC the 7900s have zero gain from the dual-pumped FP32 units because the compiler doesn't really support the functionality yet.
