[Rumor] Snapdragon 8cx Gen4, codename "Hamoa"
本帖最后由 埃律西昂 于 2023-1-22 21:58 编辑Source: @Za_Raczke
CPU:
As I previously leaked, the highest model of Hamoa has 8 performance cores and 4 power efficient ones. Qualcomm is testing the chip at ~3.4GHz (performance cores) and ~2.5GHz (efficient cores).
...
lt seems like some people/tech sites completely missed this, so l'll confirm it: yes, the CPU cores are the custom Nuvia Phoenix-based Oryon cores. What else would they be?
Cache:
Each block of 4 cores has 12MB of shared L2 cache. There is also 8MB of L3 cache.
Additionally there is 12MB of system-level cache, as well as 4MB of memory for graphics use cases.
RAM:
As for RAM, the integrated controller supports up to 64GB of 8-channel LPDDR5x with optional low-power features at up to 4.2GHz.
iGPU:
The integrated GPU is Adreno 740 - the same one as in Snapdragon 8 Gen 2. Qualcomm will be providing support for DirectX 12, Vulkan 1.3, OpenCL as well as DirectML.
PCIe:
The 12 core SKU also provides support for discrete GPUs over its 8 lanes of PCIe 4.0.
There are also 4 lanes (configurable as 2x2) of PCIe 4.0 for NVMe drives, as well as some PCIe 3.0 lanes for the WiFi card and the modem.
Connection:
The WiFi subsystem will support WiFi 7.
As for the modem, Qualcomm seems to be recommending (external) X65.
UFS:
For integrators not wanting to use NVMe for the boot drive, Qualcomm included a 2-lane UFS 4.0 controller with support of up to 1TB parts.
DSP:
Qualcomm has also updated their Hexagon Tensor Processor to provide up to 45 TOPS (INT 8) of AI performance.
They have been working with Microsoft and Adobe to make AI acceleration more useful on Windows for quite a while now.
USB I/O:
The chip also provides ample user-accessible IO: two USB 3.1 10Gbps ports, as well as three USB 4 (Thunderbolt 4) ports with DisplayPort 1.4a.
Display support:
Speaking of displays, the support has been greatly improved, and the chip can now concurrently output up to 5K+4K+4K (or different configurations with similar bandwidth).
Video encode/decode:
The video encode/decode block has also seen great improvements:
The chip can decode up to 4K120 and encode up to 4K60, including AV1 in both cases!
Great video support is what made Apple's M chips so great for video editing, so hopefully we will see this here too! 高通还是不死心啊 本帖最后由 continuing 于 2023-1-21 18:00 编辑
规格看着
8G2的GPU挺可以
就是这CPU。。8P+4E?8个3.4的X3+4个2.5的A710？那估计功耗不会太好看，8G2的X3跑3.2的单核功耗可不低 本帖最后由 埃律西昂 于 2023-1-21 18:33 编辑

应该不是，因为这位爆料人之前的说法是：
Qualcomm's working on a 2024 desktop chip codename "Hamoa" with up to 12 (8P+4E) in-house cores (based on the Nuvia Phoenix design)
不过这位之前也出过一些错误（比如认为8 Gen2是三丛集，但也提到过1+2+2+3的组合），值得关注。 这soc双烤估计要50w 埃律西昂 发表于 2023-1-21 18:03

8G2确实是三从集啊
1+4+3的嘛
nuvia应该没这么快，我觉得不太对，今年的8G3也是公版，只不过据说是1+5+2 本帖最后由 埃律西昂 于 2023-1-21 18:30 编辑

8G2是1+2+2+3啊，同时上了A710和A715。 打起来，苹果已经摆烂三年了 埃律西昂 发表于 2023-1-21 18:28
8G2是1+2+2+3啊，同时上了A710和A715。
不，实际上两个A715和两个A710是统一调度的，软件识别上也会把这四个中核当成一个丛集（64位的软件）
1+2+2+3是最开始爆出来消息的时候猜测的调度，但是出来之后大家就发现不是那么回事了
给你看下GB5识别8G2是什么情况
这应该和nuvia没关系吧 continuing 发表于 2023-1-21 18:57

那IT之家也被忽悠了，不过这种事情确实之前没见过。 埃律西昂 发表于 2023-1-21 19:02

你看原文也能看到啊
高通自己的说明都是有一个超大核，四个性能内核和三个效率内核
是IT之家自己提问说是1+2+2+3，因为那会大家只知道架构是这样，具体调度怎么样是不知道的，实际上这篇文章出来的时候所有人都没拿到实机测试，连工程机都没，极客湾出8G2视频也就是现场玩了一下。然后实机出来测试的时候才发现高通吧四个中核丢一块了 BFG9K 发表于 2023-1-21 19:02
这应该和nuvia没关系吧
主要是时间对不上
目前已知8G3还是arm小改，8G4才上nuvia，这样算的话，8CXG5用nuvia还差不多，反正PC芯片功耗可以放开一点先做出来试试能效之类的再给8G4就很合理，但是8CXG4直接用就不太对劲了 continuing 发表于 2023-1-21 19:10

看来8G3还是4nm么，看来8G2要接865的班了[流汗] 终于要暴打苹果了[偷笑]，nuvia团队要告诉库克，没有了我们，你们真的就不行了。 BFG9K 发表于 2023-1-21 19:02

我擦，那必须冲个8CX G4笔记本了 BFG9K 发表于 2023-1-22 22:03

但愿爆料正确，毕竟Arm的策略和与高通的诉讼可能影响到这类产品。
