Acer Intros Predator Bifrost Radeon RX 7900 GRE OC Graphics Card

[btarunr]

Acer introduced the Predator Bifrost Radeon RX 7900 GRE OC graphics card. This card is based on what appears to be an identical board design to its Predator Bifrost RX 7800 XT OC. Given that the TBP of both GPUs is similar to each other around the 260 W-mark, this shouldn't be a cause for concern. The card features a triple-slot cooling solution, with an aluminium fin-stack heatsink, and three Frostblade 3.0 fans with webbed impellers, designed to maximum axial airflow. The card draws power from a pair of 8-pin PCIe power connectors. Display outputs include three DisplayPort 2.1, and an HDMI 2.1. The card comes with a healthy factory OC of 2050 MHz Game clock, compared to 1880 MHz AMD reference for the RX 7900 GRE.

Based on the compacted version of the "Navi 31" chiplet GPU, the RX 7900 GRE is powered by the latest RDNA 3 graphics architecture, and features 5,120 stream processors across 80 compute units (CU); besides 160 AI accelerators, 80 Ray accelerators, 320 TMUs, and 160 ROPs. Only four of the six memory cache dies (MCDs) are enabled, so the GPU gets 64 MB of Infinity Cache, and a 256-bit wide GDDR6 memory interface, driving 16 GB of memory at 18 Gbps (576 GB/s bandwidth). Acer didn't reveal pricing.

Good to see another AIB, in the mix* and more open disclosure about the Navi 31 XL being mobile-derived/'compacted'.

After seeing only one Alienware w/ a 7900M, along with reports of AMD 7000Mseries having issues (OEM-integration garbage, IMO)
I'm left wondering if the GRE came about from cancelled 7900M orders, or lacking interest from Mobile ODMs?
At the very least, exceptional yields, maybe?

I'd be interested to see some x-ray and/or electron microscopy of these Navi31XLs in the 40x39(?)mm package (same as Navi32's pkg.size); wonder what all is "disabled" (Lasercut?) and what is "dummy'd".

So far, I'm quite impressed with my Sapphire Nitro+ GRE. Even, clocked down and undervolted to ~125W it delivers surprisingly competent performance (@ 1080P).

Which, is an entire value proposition missed w/ these Navi31XLs: They very easily can be tuned for efficiency while, still being a huge upgrade over older 250-300+W cards.
RX 7900 Nano? anyone?

*Yes, Acer makes Intel ARC GPUs also. edit: and they announced AMD cards in January '24.

I mean, I don’t care for RGB myself really, but do the names just get pulled out of a hat? Hello? Bifrost, the famously RAINBOW bridge of Norse myth?

Its weird because the A770 Bifrost is totally different.
